Another month, another melted 12VHPWR adapter on an RTX 5090 and more specifically, an MSI RTX 5090. In this most recent tale of burnt-out adapter, the head didn’t just fizzle: it fused together with the power port of the GPU.

Technical stacks shift. Hiring markets mutate. Tooling obsoletes itself every quarter. The only durable advantage is the ability to convert ambiguity into working systems faster than your peers. That isn’t creativity or talent. It’s process. Define the problem in one sentence. Strip every requirement that doesn't change the outcome. Identify the single constraint that governs the system. Build the minimum artifact that validates your assumption. Iterate only on what breaks. Eliminate everything else. This workflow outperforms brilliance, years of experience, and encyclopedic framework knowledge. It produces momentum anywhere: new jobs, new stacks, new domains. It reduces burnout by removing self-inflicted complexity. It turns pressure into throughput. Developers who internalize this stop chasing hype and stop fearing disruption. They become the stabilizing force teams rely on because they execute predictably in volatile conditions. That’s the multiplier. That’s the leverage.  ( 6 min )

Seeing Through the Shine: AI That 'Sculpts' 3D from Reflections Ever tried to 3D scan a shiny object? The reflections throw everything off, making accurate reconstruction nearly impossible. It's like trying to photograph a ghost – the data is there, but distorted. What if AI could learn to ignore the glint and see the underlying shape, like an artist sculpting clay? This is the core idea behind a new approach to 3D reconstruction. Instead of directly interpreting reflected light, a neural network is trained to translate images into a "clay-like" representation. Think of it as the AI re-imagining the object as if it were made of matte, reflection-free material. This intermediary representation, devoid of confusing specular highlights, provides a much cleaner signal for inferring the objec…  ( 7 min )

How Subtle UI Details Make Your Design Stand Out. Practical Techniques for Modern Interfaces Introduction Most UI layouts today are clean, responsive, and technically sound, but they often lack something crucial: personality. In this article, I’ll show how small aesthetic decisions, like parallax depth, environmental motion, soft textures, and micro-details can make a website feel alive. I’ll use my own portfolio as the example, breaking down exactly how I implemented each detail and why it works. Choosing a Primary UI Concept and Its Supporting Details So how do you actually do that? You start small, you think to yourself, "What am I buiding? What am I trying to portray?" With this picture in mind you can now start deciding which theme will be your main focus and which will…  ( 9 min )

Há algumas semanas, eu defini a meta de aprender TypeScript e desenvolver um produto do zero utilizando tudo o que a linguagem de programação tem a oferecer. Sendo alguém com experiência trabalhando com orientação a objetos, migrar para um ambiente multiparadigma me pareceu bastante interessante. Um dos desafios foi trazer os conceitos aplicados em aplicações C# e .NET para o mundo do Node.js, e um desses conceitos foi o Domain-Driven Design. Explicando de forma breve, Domain-Driven Design, ou DDD, é uma abordagem de desenvolvimento de software que foca na complexidade do domínio de negócio, trazendo-o para o centro do desenvolvimento e buscando aproximar os especialistas desse domínio do processo de criação dos sistemas.

For the past months, I’ve been building PyTogether, an open-sourced, real-time collaborative Python IDE designed specifically for students, education and pair programming purposes. While tools like Replit and VS Code Live Share exist, they often come with significant bloat-paywalls, complex environments, and AI copilots that can actually hinder the learning process for beginners. As a second-year engineering student myself, I wanted to build the opposite: a lightweight, communication-first environment where the code is the focus. The result is a fully free, browser-based IDE with real-time selections, voice/live chat, and shared drawing tools. It currently supports over 500 users. Here is a deep dive into the architecture, the tech stack, and the specific engineering hurdles I faced buil…  ( 8 min )

Hook: the problem and the promise You want to sell online without reinventing core infrastructure: hosting, payments, security, and scaling. Shopify promises to offload those operational burdens so you can iterate on product, UX, and growth with predictable reliability. This article explains why Shopify is worth considering from a technical perspective, what trade-offs you’ll accept, and practical tips to build fast, scalable stores and headless experiences. Shopify is a managed ecommerce platform that combines hosting, a secure checkout, payment integrations, and a rich app ecosystem. For small teams and solo founders, that means less DevOps and faster time-to-market. For engineering teams, it provides APIs to build custom frontends and integrations while keeping the heavy lifting centr…  ( 8 min )

Cloud computing provides on demand access to computing resources such as servers, storage, databases, and applications over the internet. It enables scalability, flexibility, and cost efficiency compared to traditional on premises infrastructure. In Microsoft Azure, a Resource Group is a logical container that holds related resources for a solution. Virtual machines, databases, storage accounts, and networking components can all be grouped together, making it easier to manage, monitor, and apply policies. Resource groups support lifecycle management (deploy, update, delete), role based access control, and cost tracking. In our exercise, we will demonstrate how to configure FTP server and create resource group, storage account, virtual network, Network Security Group and associate with o…  ( 8 min )

Designing High-Performance Fintech SaaS with Redis and CDNs A practical, junior-friendly guide using AWS, Kubernetes, and Nginx When I talk to teams building fintech or SaaS products, the conversation usually starts with features: “We need virtual cards.” “We need real-time notifications.” “We need a new reporting dashboard.” But most users only really notice one thing: speed. A payment confirmation screen that spins for 7–8 seconds, A dashboard that feels sluggish on mobile data, An app that occasionally “hangs” during peak hours. In finance, that’s not just annoying – it quietly erodes trust. If the app feels slow or unreliable, users wonder whether their money is safe, not whether your Kubernetes manifests are clean. In this article, I’ll walk through how I think about performance in…  ( 14 min )

Here's what I keep seeing: marketers celebrating their GA4 migration like they've crossed some finish line, when really they've just shown up to the starting blocks. The default segments Google hands you? They're fine for surface-level reporting. But if you're still relying on "Purchasers" and "New Users" to drive your strategy in late 2025, you're basically reading the CliffsNotes and wondering why you don't understand the plot. The real power in GA4 lives in custom segments. Not the ones everyone builds (we get it, you can segment mobile vs desktop). The ones that expose actual behavior patterns—the kind that make you rethink your entire funnel strategy at 11 PM on a Tuesday. I've spent the last year building, breaking, and rebuilding custom segments for clients across e-commerce, SaaS, …  ( 11 min )

For many years, I've used Process to call Terminal commands from my macOS apps. Process is an old technology, formerly known as NSTask. It works, but it's complicated to set up and it can have issues. The Swift language team have now published a modern alternative called Subprocess. Since I'm currently using Process in my Man Reader app and in my macOS Apps Step by Step book, I thought it was time to assess the new option and see if I should swap to it. I started by creating a sample project using the macOS App template. Then I added the package dependency by searching for https://github.com/swiftlang/swift-subprocess. This also adds swift-system which the ReadMe says provides idiomatic interfaces to system calls and low-level currency types. Next, I removed the App Sandbox in Target -> Si…  ( 11 min )

If you only meet Grok as the witty chatbot inside X, it’s easy to forget there’s a very serious, very expensive machine humming behind the sarcasm. Under that rebellious personality sits a frontier-scale training stack built on tens of thousands of GPUs, a custom JAX + Rust + Kubernetes system, and a data engine that continuously ingests both the open web and the firehose of X posts. This article takes a product-neutral, infrastructure-first look at Grok: how the model family is structured, how the training pipeline works, what sort of cluster you need to train something like Grok-1, and how real-time X integration actually plugs into the serving stack. Think of it as a systems engineer’s tour of xAI’s choices—similar in spirit to Macaron’s deep technical breakdowns of GPT, Claude and Gemi…  ( 15 min )

Unveiling the Hidden Geometry That Supercharges Neural Nets Ever wonder how a simple neural network can learn such complex patterns? Do seemingly random networks learn to identify objects regardless of their size or location? What if the secret lies in a fundamental, self-organizing principle that automatically encodes multi-scale understanding into the network itself? Imagine a blueprint for the universe, where every location reflects information about all locations nearby. Now, picture that blueprint spontaneously forming within your neural network as it trains. Recent discoveries suggest that neural networks, even relatively simple ones, spontaneously develop a multi-scale geometric structure during the learning process. This structure, a kind of inherent map, allows them to efficient…  ( 7 min )

Introduction For the last few weeks, I've been experimenting with something simple on the surface but surprisingly difficult in execution: Publishing a blog post to multiple platforms from inside an AI agent. Not via API scripts. Not via UI automation. Not via manual copy-paste. I'm talking about a true "write once → publish everywhere" workflow powered by MCP (Model Context Protocol). And the best part? This exact blog post you're reading right now was published through my MCP server. If you write blogs regularly—especially technical blogs—you probably deal with this: One version for Hashnode One version for Dev.to Maybe a copy for your personal site Slight formatting differences Lots of copy-paste And sometimes… forgetting to post on one platform For years, nothing has deeply solved th…  ( 7 min )

I didn't rewrite the library because it was broken - I rewrote it because I outgrew it. Five years. That's how long I've been maintaining timepicker-ui - a framework-agnostic time picker library that started as my "learn TypeScript properly" project. Last week, I shipped v4.0.0, a complete architectural rewrite that breaks almost everything. And honestly? It feels great. I didn't want to "play with TypeScript" - I wanted to learn it for real. And the fastest way to do that is to build something painful enough to expose all your mistakes. A time picker was perfect: Native was inconsistent across browsers, Material Design's version was locked to Google's ecosystem, and the component was small enough to finish but complex enough to teach real lessons. TypeScript caught …  ( 10 min )

If you follow frontier AI, you’ve probably noticed that xAI’s Grok has gone from “edgy Twitter chatbot” to a serious challenger to GPT, Gemini and Claude in barely two years. Grok now powers the AI assistant on X, appears in cloud providers’ model catalogs, and even has an ultra-premium “Heavy” tier aimed at power users and enterprises. At the same time, rumors and early reporting around “Grok 5” talk about a step-change in reasoning, multi-agent orchestration and truth-seeking features that could matter a lot if you’re choosing models for products in 2026. Grok is xAI’s family of large language models and the chatbot built on top of them, originally pitched as an AI with a “Hitchhiker’s Guide to the Galaxy” attitude—more irreverent, more willing to answer controversial questions, and dee…  ( 14 min )

En ny verklighet för textanalys i 2025 Utvecklingen av moderna språkmodeller har skapat en helt ny verklighet för alla som arbetar med texter. Från akademiska miljöer till marknadsföringsbyråer och journalistiska redaktioner finns samma grundläggande fråga: hur avgör man om en text verkligen är skriven av en människa? Det som för tio år sedan var en fråga om att hitta kopierade stycken har idag blivit en kamp mot alltmer sofistikerade LLM-system som kan formulera sig flytande, anpassa tonfall och till och med efterlikna mänsklig variation. I denna artikel görs en fördjupad analys av hur PlagiatKontroll klarar sig mot dessa nya typer av texter och hur den praktiska jämförelse av PlagiatKontroll LLM tests visar verktygets styrkor och begränsningar.

I love Vercel. The developer experience (DX) of connecting your Github, choosing your repo, and clicking deploy is magical. But I have a lot of side projects. And as soon as I need a few more resources, want to kick off a background worker, hit a bandwidth limit, the "Vercel Tax" kicks in. The pricing jumps significantly compared to the raw cost of compute. As we all know, Vercel is one big AWS wrapper. On the other hand, a $5 DigitalOcean or especially Hetzner VPS is incredibly cheap and powerful, but nobody wants to move from Vercel to this, as you've now got to deal with configuring Nginx, setting up Let's Encrypt, patching security updates, rolling automated deployments, and creating backups. I wanted the Vercel experience, but on my own hardware, and the current tools just didn't cut…  ( 7 min )

Most .NET developers meet this error at least once: An error was generated for warning 'Microsoft.EntityFrameworkCore.Migrations.PendingModelChangesWarning': The model for context 'ApplicationDbContext' has pending changes. Add a new migration before updating the database. You’re just running: dotnet ef database update …and EF Core essentially answers: “Your C# model and your migrations are out of sync. I refuse to update the database until you fix that.” This post turns that frustrating moment into an architectural superpower: You’ll really understand where this warning comes from.

tl;dr: I spent five years interviewing SA candidates at AWS. Comprehensive AWS training doesn't correlate with hire decisions. Production talk and clear thinking do. Now that I'm external, I can say it plainly: most interview prep is wasted effort. I was a Principal SA at AWS for two years. I sat on hiring panels as a Manager after that for three years. I made hire/no-hire decisions. I watched hundreds of candidates prepare the wrong way and then blame themselves for not studying hard enough. Now that I've left, I can say this plainly without corporate-speak: your comprehensive AWS study guide is doing more harm than good. We don't care if you memorized the Well-Architected Framework. We didn't care if you studied all 200 AWS services. We cared if you could think clearly about tradeoffs, d…  ( 12 min )

If you’re getting into cybersecurity, ethical hacking, or network engineering, you’ll quickly hear the name Nmap. When I started learning Nmap, it felt overwhelming - so many flags, so many scan types, so many outputs. At the same time, I’m building a small tool in Go that works like Nmap, which forced me to understand what Nmap actually does behind the scenes. This article is a simple introduction to Nmap for beginners — no assumptions, no jargon overload. Nmap (Network Mapper) is a free and open-source tool used to discover hosts, open ports, running services, OS information, and much more. Think of Nmap as a "network Sherlock Holmes" — it asks questions like: Who is online? Which ports are open? What services are running? What OS might this machine be using?

If 2023 was the year AI went mainstream, 2025 is the year the “one model to rule them all” myth finally broke. Instead of a single obvious winner, we now have a crowded frontier: OpenAI’s GPT-5.1 powering ChatGPT, Google’s Gemini 3 Pro running across Search and the Gemini app, Anthropic’s new Claude Opus 4.5, and xAI’s Grok 4 promising “the most intelligent model in the world.” Each vendor declares their model the smartest, safest, or most “agentic” — and the benchmarks look like a bowl of alphabet soup: HLE, ARC-AGI-2, SWE-Bench, GPQA, OSWorld. So if you’re a builder, founder, or power user, which one is actually the best AI model in 2025? The short answer is: it depends less on IQ points and more on what you’re trying to ship. The longer answer — and the goal of this article — is to sho…  ( 14 min )

My terminal was sluggish. Every time I opened a new tab, there was this annoying delay before I could start typing. I decided to dig into it, and with Claude Code's help, I went from a 770ms startup time to just 40ms. That's a 19x improvement. It wasn't that I accumulated too much tooling. Most things I have in my .zshrc, I needed, but each thing I tacked on added to my shell startup time. I honestly hadn't looked into this and just lived with it.

When you work on multiple front-end projects at scale, consistency and automation quickly become key. At Prisma Media, we wanted every merge request to focus on actual logic changes, not formatting or stylistic details. We had relied on the classic linting stack: ESLint for JavaScript and TypeScript, StyleLint for CSS and Prettier for consistent formatting. With VS Code Workspaces configured for auto-format on save, code reviews became cleaner and formatting discussions disappeared. This article explains how we simplified this stack by migrating to Biome, a single tool that handles linting and formatting across multiple front-end languages. Before Biome, our front-end projects relied on the classic trio: ESLint, StyleLint and Prettier. Over time, the linting stack grew to cover more langua…  ( 9 min )

Surely most people have encountered the concept of HATEOAS at least once, but what exactly is it?

AI-powered search engines are becoming the primary way people discover information online. Instead of browsing long lists of links, users now ask ChatGPT, Perplexity, Gemini, and Microsoft Copilot for recommendations — and these systems return one single, authoritative answer. That means a brand is either included in the response or ignored entirely. This fundamental shift has created demand for AI ranking tools — platforms that help businesses understand and improve how they appear inside AI-generated answers. These tools analyze visibility, track brand mentions, and reveal keyword and prompt opportunities across multiple AI engines.

The task is to implement the function Object.is() The boilerplate code function is(a, b) { // your code here } Object.is() works the same way except for 2 special cases. +0 and -0 are the same, but Object.is() says they are different. Also, NaN === NaN is false, but Object.is() says they are the same. With that in mind, if +0 and -0 look equal, check if they have the same sign. It is checked by dividing 1 by both if (a === b) { return a !== 0 || 1 / a === 1 / b; } For NaN, check if the value is equal to itself return a !== a && b !== b; The final code function is(a, b) { // your code here if(a === b) { return a !== 0 || 1 / a === 1 / b; } return a !== a && b !== b; } That's all folks!  ( 6 min )

While the West has been captivated by its own financial theater, the foundations are trembling. For nearly sixteen years since the 2008 crisis, the U.S. economy has swept its real problems under the rug, choosing instead to inflate a succession of asset bubbles. This policy created a distorted reality, masking deep-seated issues like wealth inequality and a weakening real economy. The pandemic only accelerated this process, with massive liquidity injections providing a temporary lifeline that blew yet another layer of froth onto an already precarious market. This isn't just another cycle; it's a dangerous parallel to the stagflationary trap of the 1970s, a dynamic we have been tracking for five years. The music is slowing, and the signs of a major market dislocation are now too obvious to …  ( 10 min )

As we dive into the world of synthetic data, one concept that often gets overlooked is the idea of "information-theoretic" synthetic data. In essence, this approach focuses on generating data that not only mimics the statistical properties of the original data but also captures the underlying relationships and patterns within it. This is achieved through the use of techniques like generative adversarial networks (GANs) and variational autoencoders (VAEs), which can learn to represent complex data distributions in a compact and meaningful way. The benefits of information-theoretic synthetic data are numerous. For instance, it can be used to create synthetic data that is not only realistic but also consistent with the underlying mechanisms that generated the original data. This can be particularly useful in fields like healthcare, where synthetic data can be used to create realistic patient simulations for training medical AI models. By generating data that is not only realistic but also informative, we can unlock new insights and applications that were previously inaccessible. Publicado automáticamente  ( 6 min )

This article is a less technical version of my gist about how to implement Vite + Kemal. Kemal is a minimalist Crystal web framework, inspired by Sinatra from Ruby. Its main difference from Sinatra is its speed, due to Crystal’s native compilation. Meanwhile, in the front end world, Vite appeared as an alternative to bundlers, and quickly gained attention. But what if we could combine both Vite and Kemal in the same application and use any modern UI framework, or even just simple HTML with some libraries, without manually copying .min.js files? That is why this article exists! First, install Crystal (if you do not have it) and Node.js (or Bun). After that, create a Crystal project: crystal init app app cd app Then, edit your shard.yml and add Kemal as a dependency. Here is an example: nam…  ( 7 min )

When you're building a content publishing API that already supports Twitter, LinkedIn, and Dev.to, adding WordPress feels like it should be straightforward. It's just another REST API, right? Not quite. Unlike the other platforms, WordPress doesn't use OAuth. It uses HTTP Basic Authentication with application passwords. This means instead of managing tokens and refresh flows, you're dealing with a simpler but more permanent credential system. Here's what the authentication looks like: const authString = Buffer.from(`${username}:${applicationPassword}`).toString('base64'); const response = await fetch(`${siteUrl}/wp-json/wp/v2/posts`, { method: 'POST', headers: { 'Authorization': `Basic ${authString}`, 'Content-Type': 'application/json', }, body: JSON.stringify(postData), }…  ( 8 min )

Unlocking the Potential of Dynamic Adaptive Difficulty Adjustment (DADA) in Sports Training Recent research in AI Sports Coach has yielded a groundbreaking discovery: the effective implementation of Dynamic Adaptive Difficulty Adjustment (DADA) in sports training. By leveraging machine learning algorithms, DADA enables real-time modification of training stimuli to optimize an athlete's progress, preventing plateaus and reducing the risk of over-or undertraining. Our study, conducted in collaboration with top-tier sports teams, demonstrated that DADA-based training protocols resulted in significant improvements in agility, speed, and reaction time among athletes. Moreover, a notable 35% reduction in injury prevalence was observed among the DADA-trained group compared to the control group. The practical implications of DADA are far-reaching. With the ability to continuously adjust the difficulty level of training exercises, coaches can: Improve athlete engagement: By providing challenging yet manageable tasks, coaches can maintain athletes' motivation and interest, reducing the likelihood of dropout. Enhance transfer of learning: DADA enables the simulation of real-game scenarios, allowing athletes to develop skills that are directly applicable to competition. Optimize training load: By minimizing the risk of overtraining, coaches can ensure that athletes are performing at their best, while also reducing the likelihood of burnout. As the field of AI Sports Coach continues to evolve, the integration of DADA into training protocols will undoubtedly become a cornerstone of high-performance sports development.

Maven Enforcer Rule dependOnAllProjects, com.github.mikkoi:maven-enforcer-rule-depend-on-all-projects is a user-created custom rule to force any Maven project in a multi module build to have a dependency on all other projects in the same build. The rule ensures that when a multi module Maven project is reconfigured by adding or removing subprojects, all projects are listed as dependencies for that subproject in which maven-enforcer-plugin is executed. If used in a CI pipeline or in any similar manner, this Maven Enforcer rule will keep the subproject up to date. If there is something that needs to be done after everything else in the build is completed, it can be placed into its own subproject with maven-enforcer-plugin configured with this rule.

What is HexSpeak? HexSpeak is not a single programming language, but rather a style of hexadecimal encoding where values are intentionally chosen so they form readable words when written in hex. Programs, memory signatures, or machine instructions are crafted using hexadecimal values like “0xDEADBEEF”, “0xFEEDFACE”, or “0xCAFEBABE”. These readable patterns act like inside jokes in low-level programming and hacker culture. HexSpeak is especially common in bootloaders, malware signatures, ROM headers, and compiler metadata. In some environments, code can be written entirely in hexadecimal, and HexSpeak makes it slightly more fun or memorable — even if still cryptic. Type: Encoded / Low-level style Origin: Late 1970s (home computer hacking era) Used in: Machine code, compilers, bootloader…  ( 7 min )

A human-centered argument backed by real research Imagine a world where people have one extra day every week to rest, doesn't hurt productivity --- in many cases, it improves it.

What is Chicken? Chicken is an esoteric programming language created by Torbjörn Söderstedt. The idea is simple and intentionally ridiculous: every piece of code must consist only of the word “chicken,” repeated one or more times. The number of times “chicken” appears in a line determines the instruction. Because of this, the language looks like a farm animal repeating itself endlessly. Chicken is based loosely on a stack machine, similar to languages like Brainfuck or Ook. Instead of meaningful syntax, logic is encoded entirely by counting how many times the word appears. It is absurd, difficult, and intentionally frustrating — but also strangely entertaining. Language Type: Esoteric / Joke Creator: Torbjörn Söderstedt Syntax: Only the word “chicken” Instruction Style: Count-based in…  ( 7 min )

AI is no longer a “nice-to-have experiment.” It’s quietly becoming the backbone of modern products. McKinsey’s recent survey shows that 88% of the companies now use AI in at least one business function, and major industries expect a large share of their revenue in the next few years to come from new or improved products. The good news: AI can dramatically speed up product development, personalize user experiences, and reduce guesswork. This article is written from a business perspective—not a developer’s. You don’t need to know how to train a model if you can partner with a reliable development partner – but you need to understand how to move an AI product from idea to launch in a way that is strategic and aligned with your business goals.

What is Aheui? Aheui is an esoteric programming language designed by Korean developer Yoo Eui-young. It uses Korean Hangul syllables as its instructions, making it one of the rare programming languages where code looks like written natural language. Instead of Latin characters or symbols, Aheui uses consonants and vowels as operations, storage commands, and movement instructions. The language operates on a two-dimensional grid, meaning the instruction pointer can move up, down, left, or right depending on the vowel following the consonant instruction. This gives Aheui a similar feel to languages like Befunge, but with the unique twist of using phonetic rules from Hangul. Aheui is not designed for everyday programming. Instead, it exists to explore linguistic structure as executable code, b…  ( 7 min )

What is Brainfuck? Brainfuck is a minimalist esoteric programming language created by Urban Müller in 1993. It is famous for using only eight single-character commands while still being fully Turing-complete. Brainfuck works on a tape of memory cells and a movable pointer, operating at the lowest conceptual level of computation. Because of its minimalism, even simple programs become long streams of symbols that are extremely hard to read or write. Brainfuck was never intended to be practical. Instead, it exists as a programming challenge and an intellectual puzzle, forcing developers to think differently about how instructions translate into operations.

What is LOLCODE? LOLCODE is a programming language created by Adam Lindsay in 2007 as a joke based on the writing style of early internet memes and "LOLcats." The syntax imitates broken internet grammar and humorous misspellings, making the code read like chaotic online messages rather than structured programming syntax. Despite its playful appearance, LOLCODE is a real, Turing-complete language and supports variables, loops, conditionals, I/O, and functions. The goal of LOLCODE isn’t practicality—it’s entertainment. It transforms programming into humor, making the code itself part of the joke. You don’t just write logic; you write comedy disguised as syntax.

What is Piet? Piet is an esoteric programming language created by David Morgan-Mar in 2001 where programs are written as colorful bitmap images instead of text. Instead of characters or keywords, the code consists of color blocks arranged like abstract art. The instruction pointer moves through these colored regions, and the transitions between colors determine what operations occur. The language is named after the painter Piet Mondrian, known for geometric color-block artwork. Piet is both a programming language and a visual art medium. A valid program might look like a modern art painting rather than code. Because of this, it often appears in programming challenges and showcases where the goal is to write functional yet visually aesthetic code. Language Type: Esoteric / Visual Release…  ( 7 min )

How a “boring theory subject” ended up shaping my entire AI career When I was doing my Master’s in computer engineering at the University of Padova, there was one subject everyone whispered about: Automata Theory & Computation.

You won’t always have a perfect index for every query, but may have have single-field indexes for each filter. In such cases, PostgreSQL can use Bitmap Scan to combine these indexes. MongoDB is also capable of merging multiple index bounds in a single scan or using index intersection to combine separate scans. Yet, the MongoDB query planner rarely selects index intersection. Let’s look at the reasons behind this. TL;DR: if you think you need index intersection, you probably need better compound indexes. I create a collection with one hundred thousand documents and two fields, with an index on each: let bulk = []; for (let i = 0; i < 100000; i++) { bulk.push({ a: Math.floor(Math.random()*100), b: Math.floor(Math.random()*100) }); } db.demo.inse…  ( 15 min )

05AB1E 05AB1E is a code-golf programming language created around 2015 by Adnan. The goal of the language is to make programs as short as possible, even if the code looks strange or unreadable. It uses a stack-based execution model and many operations are represented by single Unicode characters. Language Type: Code Golf Difficulty: Hard Typing: Dynamic Execution Style: Stack-based / Implicit output Example (Hello World): "Hello, World!" This prints automatically because the language assumes output. How It Works: Most instructions are one character. The language uses a stack instead of variables. Printing is automatic, so you don’t need print statements. Where to Run: You can run 05AB1E at TIO.run online. Should You Learn It? Useful for jobs: No Useful for fun and challenges: Yes Good for readable code: No Summary: 05AB1E exists for people who enjoy writing the shortest possible solution. It’s fast, clever, and chaotic.

Good product filters are invisible when they work well and super annoying when they don’t. Almost everyone has rage‑clicked their way through a bad filtering system, wondering why nothing seems to match what they actually want. The first step is understanding how people think about your products. Are they comparing by price, size, color, category, use case, or something else? Talk to users, watch how they browse, and notice what questions they ask before deciding. Those mental criteria should guide your filter options. When you're selling products online, clutter is the enemy. If you offer 25 different filters on one side of the page, most people will ignore them. Start with the essentials — maybe price range, category, and 2–3 key attributes that really matter. You can always add advanced filters in a collapsible section for power users. The language you use for filters matters, too. Technical or internal terms confuse people. Labels should match the words your customers naturally use, not whatever’s in your database schema. If someone says “hoodie,” don’t make them choose between “fleece top” and “mid‑layer garment.” Speed is another big factor. Filters should respond quickly, ideally without making the user reload an entire page every time they click something. If there are no matching results, say that clearly and give a way to reset or adjust filters instead of just showing an empty grid. Order also plays a role. Putting the most commonly used filters at the top and grouping related options together makes the whole experience feel calmer. Testing different layouts with actual users — even informally — can reveal surprising preferences. When filters are thoughtfully designed, shopping feels more like “finding what fits me” and less like “fighting a website.” That calmness turns casual browsers into confident buyers.  ( 7 min )

A few weeks ago, I was helping a close friend set up her new online store. She sells handmade soaps, each one carefully crafted with pastel colors that look like they came straight out of a mood board. For her website, she wanted everything to feel soft, warm, and comforting. She handed me a Pantone card—a dusty rose shade she absolutely adored. I took the card home, held it under my desk lamp, admired the texture and warmth of the shade… and then made the mistake almost every digital designer makes at least once. I guessed the HEX value.

I've been working with ActiveFields, a gem for handling dynamic fields using the Entity-Attribute-Value (EAV) pattern. One of the challenges with EAV is querying those custom fields efficiently. ActiveFields includes a search feature that handles this, and I thought I'd share how it works. When you store custom fields in an EAV pattern, searching becomes tricky. You need to handle type casting, field-specific operators, and construct queries efficiently. ActiveFields provides a unified search interface that supports all built-in field types. The main method is where_active_fields, which supports all 13 built-in field types with type-specific operations. The method accepts three different input formats: 1. Array of Hashes - useful for programmatic queries: Post.where_active_fields([ { nam…  ( 9 min )

I quit AI for 30 days and found something I didn’t expect: my brain still had opinions. I didn’t plan to quit AI for 30 days. It just sort of… happened after I made a ranty video about why AI coding feels wrong lately. You know the type the “Copilot just hallucinated an entire database schema again” vibe. At the end of that video, I said I’d take a month-long break from AI tools. Viewers dared me to actually do it. My pride said “yeah, easy.” My brain, on day one, immediately disagreed. Because for the past couple years, AI has slipped into my workflow the way energy drinks slip into a LAN party: quietly at first, then suddenly you feel like you can’t function without it. Autocomplete becomes a reflex. Explaining bugs to ChatGPT becomes emotional therapy. And when you disable all of it, y…  ( 12 min )

In 2025, the "Modern Stack" of Next.js, Tailwind CSS, and API-first development has become the industry standard for building scalable, high-performance web applications. Next.js serves as the backbone, offering a hybrid architecture that blends the speed of server-side rendering with the interactivity of client-side React, while its App Router simplifies complex routing and data fetching. Tailwind CSS complements this by enabling a utility-first workflow that streamlines responsive design directly within the markup, significantly reducing context-switching and development time. Finally, the shift toward an "API Economy" means developers are increasingly orchestrating specialized services—for authentication, content, and payments—rather than building monolithic backends, making proficiency in asynchronous data handling and state management a critical skill for the modern frontend engineer.  ( 6 min )

I swear every time I open a Dockerfile, I get the same feeling as when I open my fridge at night: I know something cursed is in there, I just don’t know where it’s hiding. Dockerfiles are like the “draw the rest of the owl” meme for developers. One minute everything is fine, the next you’re staring at a 3GB image that takes longer to build than Baldur’s Gate 3’s character creator. Anyway this whole article started because last week, during a perfectly normal deploy, the container image ballooned from 900MB to 1.7GB after merging one “small change.” And by “small,” I mean someone added a single RUN command that installed half of Ubuntu. A senior dev did that. A good senior dev. A senior dev who I would trust with my production database but apparently not with apt-get . And it reminded me of…  ( 10 min )

A Major Cryptographic Upgrade for Modern Security Standards Posted by Muhammed Shafin P (HejHdiss) | Qeltrix Project Lead I'm excited to announce Qeltrix V4, a focused cryptographic upgrade that marks a significant milestone in the Qeltrix ecosystem. This release represents a deliberate break from backward compatibility in favor of adopting industry-standard, hardware-accelerated encryption that meets modern security requirements. AES256-GCM as the Core Cipher V4 makes a fundamental shift from ChaCha20-Poly1305 to AES-256-GCM (Advanced Encryption Standard with Galois/Counter Mode) as the sole bulk encryption algorithm. Why AES256-GCM? Industry Standard: Widely vetted, NIST-approved, and certified for government use Hardware Acceleration: Native CPU support via AES-NI on modern processors…  ( 18 min )

Terraform relies on a state file to understand the infrastructure it manages. Instead of constantly querying cloud providers which is slow, expensive, and inefficient Terraform stores the current state of your resources locally or remotely. This file acts as Terraform’s “source of truth,” enabling it to detect changes, manage dependencies, and apply updates safely. Terraform’s state file records the attributes and relationships of your deployed resources. It allows Terraform to: Compare desired configuration vs. actual infrastructure Generate accurate execution plans Track dependencies between resources Enable collaboration across teams Because Terraform relies heavily on this file, keeping it secure and consistent is critical. To avoid corruption, security risks, or inconsistent deploymen…  ( 7 min )

Building AI agents is fun. Building the long-term memory (RAG) infrastructure for them? Not so much. Every time I started a new side project, I hit the same "Boilerplate Wall": Spin up a Vector DB (Pinecone/Weaviate). Write the embedding pipeline logic. Figure out chunking strategies. Debug why the agent retrieves context from 3 months ago instead of yesterday. I realized I was spending 80% of my time on plumbing and only 20% on the actual agent. So, I decided to abstract it all away. I built MemVault, a "Memory-as-a-Service" API wrapper around PostgreSQL + pgvector. Here is why I chose this architecture, how the hybrid search algorithm works, and why I built a visualizer to debug the "black box". I didn't want another expensive SaaS subscription, and I didn't want to manage a complex …  ( 8 min )

On November 18th, 2025, Cloudflare had what they describe as their worst outage since 2019. It didn't start with a cyber attack or massive hardware failure. It started with a database permissions change. This is exactly the sort of thing Continuous Delivery is supposed to make safe. So since the post-mortem came out I wanted to analyze it through a CI/CD lens. Around 11:20 UTC, Cloudflare’s network started returning a huge spike of HTTP 5xx errors for traffic flowing through their core network. Users all over the Internet started seeing Cloudflare error pages instead of the sites they were trying to visit. The root cause was a change to how one of their ClickHouse database clusters handled permissions and metadata. Here’s the rough chain of events: Cloudflare deployed a change to ClickHous…  ( 11 min )

Most developers rely on GitHub as the single source of truth for their work. That’s fine—until it isn’t. Repos get deleted, teams reorganize, permissions change, and old code quietly disappears. Farmore solves that problem in the simplest way possible: It backs up everything you own on GitHub in one go. No platform dependence. No manual cloning. No “I’ll do it later.” Just a complete mirror of your GitHub activity saved locally, whenever you want it. Farmore’s goal is straightforward: Give developers an easy, reliable way to back up their GitHub repos and related data. Here’s what it brings to the table: 1. Automatic full-account backups Tell Farmore whose account you want to back up—yours or an organization’s—and it pulls all repositories for you. Public, private, starred, watched, f…  ( 7 min )

In today’s hyper-connected world, organizations generate an overwhelming amount of data—from user activity and network traffic to application logs and cloud telemetry. Hidden in that data are the early warning signs of cyber threats. The challenge is making sense of it all. That’s where SIEM, or Security Information and Event Management, enters the picture. A SIEM platform acts as the central nervous system of an organization’s security operations. It collects, correlates, and analyzes security events from across your entire IT and OT environment, helping security teams detect threats, investigate incidents, and maintain compliance. But SIEM isn’t just a tool—it’s a strategic component of the broader cybersecurity stack. What Exactly Is SIEM? A SIEM system performs three fundamental func…  ( 8 min )

What is Cutout? Cutout might be one of the few augmentations that looks wrong at first glance. A square. Introduced in 2017, Cutout asks a bold question: “What if we deliberately hide a portion of your training data and force the model to deal with it?” No fancy tuning. Why does removing information help? Deep networks love shortcuts. Cutout’s mask breaks those shortcuts. By erasing a random portion of each training sample: Local features cannot be fully trusted The model must build distributed, global representations Robustness improves because inference almost always sees unmasked images This “forced generalization” effect is surprisingly effective, especially on small/medium datasets. Why doesn’t Cutout ruin training? Two reasons: The masked region is small relative to the full image Occlusion is consistent with real-world noise It’s structured chaos. When does Cutout struggle? Cutout begins to underperform when: Fine-grained details matter The masked region wipes out key class-defining features The dataset already contains natural occlusion The mask size is tuned poorly Still, as a single-component augmentation, Cutout remains remarkably useful and computationally near-free. Conclusion Cutout is the simplest form of feature dropout: Next up: CutMix, the augmentation that asked: “What if we don’t remove pixels… but replace them with pixels from another image?”  ( 7 min )

Say you have a data lake. How do you get known-good CSV or Excel files into it? CsvPath Framework has a few options: Locate the archive on the local disk, within the lake Use a backend to stream to the lake during processing Use the SFTP integration to forward files after processing is done Use transfer-mode to forward files after processing All good options. Each serves particular use cases, though with quite a bit of overlap. Local processing is of course the fastest, so making CsvPath Framework essentially be the bronze layer of a local data lake is common. In this scenario, the archive(s) are the part of the lake that handle data files. Alternative, any remote backend (s3://, azure://, gs://, sftp://) can receive data as it is generated.

Earlier this year, I was amazed by agentic AI coding with Claude Sonnet 3.7. The term "vibe coding" hadn't been coined yet, but that's exactly what I was doing—letting AI generate code while I steered the conversation. It felt magical. Until it didn't. After a few weeks, I noticed patterns: code redundancy creeping in, intentions drifting from my original vision, and increasing rework as the AI forgot context between sessions. The honeymoon was over. I needed structure, but not the heavyweight processes that would kill the speed I'd gained. That search led me through several existing tools—Kiro, Spec Kit, OpenSpec—and eventually to building LeanSpec, a lightweight Spec-Driven Development framework that hits v0.2.7 today with 10 releases in under three weeks.

Save the planet and adapt the LLM to your use-case! The process of reducing a Large Language Model (LLM) to FP4 (4-bit Floating Point) precision is a quantization technique primarily used to drastically decrease the memory required and accelerate inference (text generation), allowing larger models to be run on less powerful hardware, such as a single desktop GPU. Practically, this is typically achieved by utilizing specialized libraries — like bitsandbytes—that integrate directly with machine learning frameworks such as PyTorch and the Hugging Face Transformers library. This technique directly supports a “greener” or more sustainable AI approach by significantly reducing the energy consumption required during the model’s inference phase. Since 4-bit quantization reduces the model’s size b…  ( 16 min )

Terraform is a binary that has no clue where or what to provision. All that it does, all its buckets, all its VPCs, all its resources, would not occur at all without a provider knowing how to communicate with a particular API. Role of Providers (The Real Terraform Workhorse): Those definitions as well as the way to send API calls to AWS are provided by AWS provider plugin. There are three important things that a provider does: Explorers are in between your Terracode and the AWS API. What developers are used to disregarding was pointed out: I today had to practice pulling configuration blocks out of the docs as opposed to guessing. This immediately minimizes errors and version conflict. Provider Versioning: Unless you pin versions, your setup may you give silent failure on a later terraform init. = 1.2, < 2.0 - version range In a modern day, I configured my AWS provider in the following way: This is so that Terraform pulls only compatible plugins.

Decision trees and decision matrices are intuitive representations of complex IF-ELSE logic for business users and are the most common and useful parts of a rule engine. Popular rule engines such as Drools do offer richer feature sets, notably the so-called RETE algorithm for efficiently reusing frequently repeated expression fragments; however, in real-world business applications the need to use the RETE algorithm is rare. In most cases we downgrade the rule engine to decision tables and decision matrices. A reasonable ordering of nodes in decision trees and decision matrices already provides execution optimization. In scenarios that truly require the RETE algorithm, it is typically difficult for most people to grasp intuitively, making it unsuitable for direct configuration by business u…  ( 10 min )

Motivation is unreliable. Here’s how devs actually build momentum one stupidly small win at a time. I used to wake up already losing. Thumb opens a feed before my eyes fully boot, brain gets hit with 200 opinions I didn’t ask for, and suddenly I’m “too tired” to touch the repo. Sound familiar? The irony: I kept waiting for motivation like it was a dependency to install. It’s not. The fix wasn’t a new app or a guru routine. It was lowering the bar until it felt embarrassing not to step over it. One line PR. Open the doc. Put on the shoes. That’s it. Something changed recently: the collective fatigue around infinite feeds. Everyone’s quietly admitting the algorithm is farming attention, and a lot of us devs are feeling weirdly “busy” while shipping less. Same. So I ran a set of tiny experim…  ( 12 min )

Apprentissage adversarial en temps réel : défis et percées L'apprentissage adversarial en temps réel bouleverse la sécurité des systèmes d'IA. Il suscite admiration et inquiétude chez les ingénieurs et les dirigeants. De plus, la nécessité d'une latence ultra-faible et d'un débit élevé impose des choix techniques rapides. Dans ce contexte, les entreprises n'ont plus droit à l'erreur : elles doivent intégrer des modèles qui apprennent à contrer des attaques en direct, tout en maintenant une précision supérieure à quatre-vingt-quinze pour cent, en réduisant la latence totale de centaines de millisecondes à des millisecondes fractionnaires, et en soutenant un débit supérieur à cent trente requêtes par seconde ; c'est une course contre la montre qui touche la confiance des utilisateurs, la c…  ( 11 min )

O Problema Lembra daquele app que começou rápido e depois foi ficando mais lento conforme adicionávamos features? Pois é, o culpado quase sempre é o mesmo: change detection. O Angular, por padrão, é um pouco paranóico. A cada evento (scroll, clique, timer), ele verifica TODA a árvore de componentes pra ver se algo mudou. Traduzindo: se você tem 100 componentes e 100 eventos por segundo, são 10.000 verificações por segundo. Não tem CPU que aguente! Para resolver, listei abaixo 5 técnicas para melhorar a performance do seu app Angular. Algumas delas, mesmo sendo velhas conhecidas, ainda hoje costumam ser ignoradas. Compatibilidade: Angular 2+ Impacto: Reduz change detection em ~90% Essa aqui muda o jogo. O OnPush faz o Angular ser mais inteligente - ele só verifica mudanças quando realmen…  ( 8 min )

Today's exam was apparently very difficult. I say "apparently" because I honestly couldn't tell. My classmates walked out devastated. Like genuinely upset. Talking about how brutal it was, how they definitely failed, how unfair the questions were. And I'm just... whatever about it. Not because I'm smart or prepared or confident. I studied for maybe 3 hours like I do for every exam. They all feel the same to me at this point—show up, write what you know, leave. Some people would call that careless. Maybe it is. But it's working so far. I'm liking this phase. Not the exam stress part—that's still there. But something else. I'm getting over the whole "stay in bed when I feel shitty" thing. Used to be when things got bad, I'd just rot. Lie there, scroll, feel worse, repeat. But lately when I f…  ( 7 min )

Python's standard logging module is capable, but shaping it into a system that produces structured, contextual, and queryable logs requires understanding a lot of concepts: hierarchical logging, formatters, filters, handlers, and configuration files. It can be done, but it often feels like you are building infrastructure instead of writing your application. Structlog takes a different approach. Rather than wrestling with object hierarchies, you simply declare how each event should be processed and enriched. The result is logging that feels natural to write, while producing output that works just as well for humans skimming a console as it does for machines ingesting JSON into an observability platform. This guide takes a practical look at using Structlog as the foundation for a production-…  ( 18 min )

We All Hate Free Trials (Well, I Do) Sometimes I just want to test something new. Maybe it’s a new AI image tool, a premium API, pay for a digital content to a creator, some data service everyone won’t shut up about. But nope—the first thing I see is “Start your 7-day free trial!” Great… except now I have to hand over my card on day one. Then I spend the whole week stressing that I’ll forget to cancel and get slapped with a $99 charge for something I used only once. Even worse: sometimes I want my AI agent (ChatGPT, Claude, Grok) to use that service for me. Which means what—give my card to the AI? I’m reckless, but an AI agent is probably ten times more reckless than me. It’s dumb. We shouldn’t need credit cards just to test stuff.

I never expected AI to become my calm-down tool. But my mental reset button? Tech isn’t always a peaceful place. There’s pressure, speed, too many ideas, too many tabs open (in browsers and in life), and the constant background noise of “learn this” / “ship that” / “don’t fall behind.” Somewhere in the middle of that storm, AI became… my slowdown. 🌫️ When your brain is overloaded, AI becomes the quiet friend I’m not a developer, but I spend enough time around tech people to know one thing: Their minds never stop.

Unlocking Algorithmic Elegance: AI's Blind Spot and the Power of Evolutionary Mappings Imagine needing to translate between two languages, not word-for-word, but conceptually. Or optimizing a complex supply chain where seemingly unrelated actions perfectly balance each other. These scenarios highlight a fundamental challenge: finding the perfect one-to-one mapping between distinct entities – a bijection. While AI excels at many tasks, discovering these elegant algorithmic relationships often remains stubbornly difficult. The core idea is to leverage a collaborative approach where AI generates possible solutions (as functional code), and then an evolutionary algorithm intelligently refines them. Think of it like breeding algorithms for speed and efficiency. The evolutionary process introd…  ( 7 min )

Executive Summary In event-driven and distributed architectures, preserving the order of messages is critical for maintaining state consistency, processing accuracy, and system reliability. Google Cloud Pub/Sub offers ordering keys to ensure that messages with the same key are delivered in the order they were published. However, this feature does not always ensure in-order delivery at the subscriber level, which is particularly critical for platforms where sequence integrity is vital (e.g., financial systems, event sequencing). This paper outlines the causes behind unordered message reception of Google Pub/Sub despite the use of ordering keys and outlines a practical solution involving subscriber-side message sorting to enforce the expected message sequence.

Angular Aria vs Angular Primitives: What’s the Difference and When Should You Use Each? The Angular ecosystem is evolving rapidly, especially around headless UI, accessibility, and composable component design. Two major players in this space are Angular Aria (introduced officially in Angular 21) and the Angular Primitives community library. At first glance they may seem similar — both provide unstyled, headless building blocks for creating highly customizable UI components. But they actually solve different layers of the UI problem. Understanding how they differ, where they overlap, and how to use them together is key if you’re building modern Angular applications, design systems, or complex custom UI libraries. This article breaks it all down. Angular Aria is an official Angular package…  ( 9 min )

There is a difference between running code and reading the world through code. Most beginners think of programming as a series of instructions to make a machine behave. Professionals understand something far more interesting. Code is a sensor. Code is a lens. You can use it to observe patterns that are otherwise invisible. You can build systems that listen to the real environment of machines, networks, services, and human activity. System awareness is the discipline of perceiving signals before they turn into problems. It is the craft of understanding that everything emits data, everything leaks state, and everything is part of a larger motion that can be measured, modeled, and interpreted. This field sits between observability engineering, security monitoring, incident response, threat hu…  ( 13 min )

AWS ECS Managed Instances: The Middle Ground We've Been Waiting For If you've been operating containerized workloads on AWS, you've probably grappled with a known trade-off.

Hey DEV community, I’m trying to build a small utility to quickly check my FAB Bank balance without opening the mobile app every time. I’m curious if anyone here has done something similar—maybe via an API, a web automation script, or some kind of lightweight app. A few questions I have: Are there public or semi-public endpoints for retrieving balance info safely? Would you handle this through a server-side script, or directly in a client-side app? Any tips for keeping credentials secure while still making it convenient to check balances? I’m mostly doing this for personal convenience, but I’d love to hear what approaches other developers take for similar tasks. Thanks!  ( 6 min )

I used to handle dependency inversion with Inversify, but I was constantly annoyed by two main things: You have to import the @inject decorator everywhere, which ends up polluting your domain code. Writing the boilerplate dependency binding code was so repetitive that I wished I could just type a single command — arise — and have it done automatically. That's why I decided to create my own DI container, coupled with a command-line interface that handles code analysis (via AST parsing) and generates the registration boilerplate for you. Some of the Features: No decorators and no vendor lock-in. ioc-arise supports injecting typed objects, factory functions, and classes implementing interfaces or inheriting abstract classes. Multiple lifecycles: singleton and transient. The CLI can detect them if you leave a JS code comment (@scope singleton or @scope transient) just above the function or object declaration.

In the traditional music production landscape, the distance between a cognitive idea and a rendered audio file is vast. A composer does not merely need a melody; they require proficiency in music theory, instrument physics, and Digital Audio Workstation (DAW) signal flow.

AWS… there’s a lot of buzz about it in the tech world. Everyone says it’s a valuable skill, companies want it, salaries go up with it — all that good stuff. But the real question is: What actually is AWS? Sure, I could tell you it’s a “comprehensive cloud services platform that offers scalable computing solutions” and blah blah blah… 😴 …but let’s be honest. “Bro, what is all this? Why so many??” 🤦 And eventually you might feel overwhelmed, bored, or even give up on AWS before you really start. So we’re not doing that today. Instead, we’re going to understand the big picture behind AWS — in the simplest, friendliest way possible — by talking through three main topics: What kind of problems do we face when we don’t use a cloud provider like AWS? How AWS solves those problems and saves u…  ( 18 min )

Recently, a friend of mine - a fintech startup founder - decided to enable in-app$BTC storage for his clients. I warned him: force users to deal with seed phrases, and you'll lose 80% of them at onboarding! We’ve all got used to unlocking iPhones with Face ID and confirming payments with a fingerprint, and I believe crypto in 2025 should feel just as effortless. Look at ZenGo: they replaced seed phrases with MPC technology, allowing wallet recovery via facial recognition. That is the standard we should aim for - and now, thanks to Wallet-as-a-Service (WaaS) infrastructure, it has become scalable for every business 🔥 👉 Take WaaS from WhiteBIT, for example. Users finally experience crypto as it should be - passwordless and secured by biometrics, free from the headache of private keys. Companies get a compliant, scalable backend layer and can instantly expand their product functionality with crypto to drive new customer streams. Easy and passwordless access is the new norm I expect from every modern financial app today. And with solutions like WaaS, any fintech can actually deliver such top-tier crypto UX without rebuilding its entire architecture.  ( 6 min )

In a world where disruption is the norm and digital boundaries are dissolving by the minute, security can no longer be an afterthought or a static layer applied at the end of an initiative. Indeed, by 2025, 52% of organizations report having fully deployed a Zero-Trust architecture, and another 38% are in partial implementation, according to recent data. Meanwhile, the financial stakes have never been higher: the global average cost of a data breach dropped to US$4.44 million, but that decline masks a more complex reality. In certain regions, the numbers are stark: in India, for example, the average breach cost surged to ₹22 crore (≈ US$2.7 million) in 2025, a 13% year-over-year rise. The organizations navigating this evolving threat landscape with confidence are the ones embracing a…  ( 12 min )

Probabilistic Graph Neural Inference for bio-inspired soft robotics maintenance in hybrid quantum-classical pipelines It was during a late-night research session, while studying octopus locomotion patterns for a bio-inspired robotics project, that I had my breakthrough moment. I'd been struggling with predicting maintenance needs for our soft robotic actuators when I realized the fundamental limitation: traditional neural networks were treating each component as independent, ignoring the intricate dependencies and probabilistic relationships that govern biological systems. This realization led me down a fascinating path of exploring probabilistic graph neural networks (PGNNs) and their integration with quantum computing for predictive maintenance. During my investigation of octopus arm c…  ( 12 min )

I have been learning Rust for a couple of years, and using it for pet projects and demos alike. Working for a JVM-heavy company, I thought it would be my fate forever. Last week, I had a nice surprise: I convinced my management that using Rust for a particular project was the right choice. It's not a huge project, but I want to describe my experience using Rust in a "real" project. Our main software platform has baked-in health sensors for monitoring. These sensors are exposed as HTTP APIs. The problem is that most customers do not actively monitor those endpoints. For an engineer such as myself, they are responsible for their lack of maturity regarding observability; for customer success managers, they should be helped and cared for. The goal is simple: provide a component that polls the …  ( 11 min )

You've probably heard about Angular's standalone components - they're a fresh way to build apps without relying on NgModules. But there's more to them than just skipping modules.

Best practices, they are not as important as you think they are. They do not just apply to the code you write to get your app to work. They also apply to styling, they apply to testing. You can implement best practices in a multitude of ways into your app, but should you? Please support my original publication here: Best Practices Are Not As Important As You Think They Are The main purpose best practices serve is code quality. You want maintainable code that you can always go back to, understand what it does, and easily swap out. Good practices make communicating with other developers way easier if you all have a certain standard, a code quality that you can all refer to. That is especially useful if you work in teams. If you work solo, not as much, but it still helps in some cases. Risk i…  ( 9 min )

When our startup first began scaling our web service, cybersecurity was not our primary focus — until an incident made it painfully clear how vulnerable we were. Like most small teams, we initially relied on a traditional WAF powered by ModSecurity, which is common across 80% of web applications worldwide. At first glance, it seemed to work: SQL injections were blocked, XSS attacks were detected, and the dashboard showed all green. But very quickly, we ran into problems. Here’s what we experienced in real life: Attacks slipping through: Even though our WAF had rules like union[\w\s]?select for SQL injection and \balert\s for XSS, attackers could easily bypass them with simple tricks. For example, inserting comments, using character encoding, or splitting keywords. False positives aff…  ( 8 min )

You need some kind of non-volatile memory – something that doesn’t lose data when power is removed. On Arduino there are a few common options: 1. Use the built-in EEPROM (simplest) Boards like Arduino Uno / Nano / Mega have a small EEPROM on the chip (typically 1–4 KB). Good for: Small amounts of data: settings, counters, calibration values, last state, etc. A few bytes to a few hundred bytes. Key points: Survives power loss / USB unplug. Limited write endurance (typically ~100,000 writes per cell) → don’t write in a tight loop. Basic example (store a value and read it after reset/power-off): #include int addr = 0; void setup() { Serial.begin(9600); // Example: write a number once (only if not initialized, etc.) int valueToStore = 42; EEPROM.put(addr, valueToStore); …  ( 7 min )

We all know the feeling. You’ve just architected a brilliant feature. The logic is sound, the data flow is elegant, and you’re ready to dive into the "fun part"—building the core functionality that actually does something cool. But wait. First, you have to build the gatekeeper. You have to check if userId exists. You have to check if age is actually a number. You have to make sure quantity isn't negative, and that email actually looks like an email. Before you know it, the top 20 lines of your function are a messy soup of if statements, typeof checks, and manual error throwing. Input verification is critical for security and stability, but it's probably also the most boring part of web development. It could break your flow, clutter your code, and turn a creative process into a tedious chor…  ( 10 min )

Over the past year, the conversation around AI inside enterprises has shifted. Teams are no longer asking whether AI can help with individual tasks—they're asking how AI can act on their behalf, move work forward, and make decisions without constant supervision. This is where agentic AI comes in. Agentic AI refers to systems that can observe what's happening, reason about the situation, take action, and learn from the outcome. Instead of waiting for a prompt, these agents proactively handle multi-step, often messy workflows—checking data, following policy, coordinating across systems, and asking for approval only when needed. It's a clear step beyond traditional generative AI, which is powerful but fundamentally reactive. For developers, this is your moment. While enterprises care about r…  ( 7 min )

The tokenization of real-world assets is steadily becoming an important part of modern finance. Institutions, fintech firms, and DeFi platforms are bringing treasury bills, real estate, credit products, and other financial instruments onto blockchain networks. This shift is not happening overnight, but the progress is consistent and meaningful. Behind this growth are two essential components that keep these markets organized and accessible. Stable coins give participants a reliable way to move value on-chain. On-chain identity helps platforms follow regulatory requirements while protecting user trust. Together they create a strong and practical foundation for the RWA ecosystem. The idea of tokenizing real-world assets works best when the supporting infrastructure is dependable. Stable coins and on-chain identity provide that dependability. Each one plays a separate role, yet both work together to create a balanced and efficient market environment. Their combined strengths help make tokenized assets easier to use, easier to manage, and easier to integrate with traditional financial systems. • Smooth transactions with verified users • Transfers restricted to approved participants • Automatic compliance through smart contracts • Consistent user experiences across regions • A strong base for long-term market growth This partnership allows RWA platforms to expand with clarity and trust. Stable coins provide global liquidity, and on-chain identity ensures regulatory alignment. The result is a stable and accessible environment that supports responsible growth. Together they reduce complexity, support transparency, and strengthen the entire ecosystem. Stable coins deliver efficient and predictable transactions. On-chain identity provides secure and compliant participation. Their combined role helps drive confidence, sustainability, and long-term success in the advancing RWA market.  ( 8 min )

House-hunting can get messy very quickly. You visit several places in one afternoon, collect brochures that all look the same, and scribble notes that eventually get lost or smudged. By the time you get home, the details start blending together. It becomes hard to remember: which one had the damp bathroom which one you actually liked and which one you ruled out but forgot why For years, I wished there was one simple tool that helped me keep everything organised — notes, photos, impressions, and reminders — all in a clean flow. Nothing existed, so I kept making do with paper, my camera roll, and memory. The frustration was real, and because I’m solving my own problem, I understand the user’s pain points deeply. The app must: Get the latest open homes from real estate's website for the weekend (TradeMe New Zealand) open instantly work offline inside houses with bad reception save notes without lag store photos and impressions together sync automatically when I’m back home Once these product constraints were solid, the technology naturally followed. A lightweight Node.js backend provides clean APIs. Offline-first storage like SQLite or Supabase solves the spotty reception issue. A simple folder structure keeps the project maintainable. And a sync layer ensures everything stays consistent across devices. What makes this project meaningful is that I’ve needed this app for a long time. I’ve had so many Saturdays where I thought, “Why doesn’t something like this exist already?” Now that I’m learning more about mobile and backend development, I can finally build the tool I’ve always wanted. It may not be perfect yet. It may take time. And I’m learning as I go. But it feels incredibly empowering to create something that solves a real frustration in my daily life. This is why I enjoy mobile development so much - it is very rewarding to solve a real life problem, as well as carry it in your pocket!! :)  ( 7 min )

Intro I decided to write this article after a year and a half of actively using AWS CloudFormation across two separate products. Because it’s less popular than Terraform, finding solutions to some problems often meant piecing together hints from different sources. Here I’ll share my experience in the hope that it helps someone else solve their CloudFormation challenges. A large part of this article is code. It’s mainly a note for myself in the future, so I can remember how I used AWS CloudFormation if I need to work with it again. When you work with CloudFormation, there are some key differences from Terraform. For example: there’s no automatic drift remediation, deployments are all-or-nothing (no partial apply), you can’t deploy to multiple regions in one go, and stack policies have th…  ( 9 min )

Then vs. Now Five years ago, analysts relied on endless video hours and physical notebooks to convince managers of their insights. Today, before an analyst finishes their morning coffee, AI has already analyzed opponents, quantified pressing triggers, and predicted scorelines. The Rise of Predictive Engines While legacy providers like Opta gave us data, new platforms like FootballAnt, Predicd, and Aiscout tell machines to predict the game. FootballAnt is probably the clearest example. Before every Champions League and major league fixture, the platform now feeds 200+ data points per team (pressing intensity, progressive pass clusters, goalkeeper sweep angles, even weather-adjusted expected threat) into its AI engine. Thirty seconds later it returns predicted scoreline. The New Role: "AI Translator" The industry has shifted from data collection to interpretation . Modern analysts now spend 70% of their time on: Translation: Converting AI insights into language managers trust. Deception Detection: Spotting when teams hide tactical patterns. Application: Designing drills that fix specific weaknesses. The Bottom Line AI did not kill the analyst; it automated the repetitive data recording . The best analysts of 2025 aren't those who watch the most minutes, but those who understand the context the machine missed.  ( 6 min )

Social engineering attacks that bypass our technical defenses by targeting the one element that can’t be patched: human psychology. After delivering lightning talks on this critical topic to enthusiastic audiences, I’ve realized that understanding social engineering isn’t just important for IT professionals—it’s essential for everyone in our increasingly digital world. Social engineering is the psychological mani…  ( 10 min )

Setting: Fitzroy café. Afternoon sun. Coffee that tastes like punishment. JAMES: Supreet, hiring in Melbourne is a nightmare. Everyone wants “top engineers,” no one can find them. And when they do, the person quits in six months for a 20k bump. I’ve never seen the market this thin. SUPREET: Yeah, I’m hearing the same from clients. And honestly—this isn’t new to me. I lived a version of this in Indonesia back in 2015. JAMES: What happened there? SUPREET: We were trying to build a cloud team for a client. AWS was taking off, but Jakarta didn’t have many cloud engineers. Maybe ten people in the whole market who had touched EC2. Singapore companies were paying double. Local companies couldn’t compete.

A Service in Kubernetes is an object that provides a stable IP address, DNS name, and consistent network access to a group of Pods. Because Pods are temporary — they die, restart, or get new IPs — a Service makes sure that: ✔ Applications can find and talk to Pods reliably ✔ Network traffic is load-balanced across Pods ✔ The communication remains stable even if Pods change Why Services Exist Pods are not permanent: Their IPs keep changing Pods come and go during scaling New Pods replace old Pods during deployments Without Services, apps would have no stable way to reach Pods. A Service hides Pod changes behind a fixed, reliable endpoint. What a Service Provides 🔹 Stable ClusterIP A virtual IP that does NOT change. DNS name Example: myapp.default.svc.cluster.local Load balancing Traffic is automatically distributed to healthy Pods. Service Discovery Apps always know how to find each other. How Services Work Internally A Service selects Pods using labels: selector: app: myapp Then Kubernetes creates: Endpoints/EndpointSlices = list of Pod IPs behind the Service Rules in kube-proxy (iptables/ipvs) to route traffic When you access the Service IP → kube-proxy forwards the request to one of the matching Pods. One-Line Interview Definition A Service in Kubernetes is a stable networking endpoint that provides consistent access, load balancing, and discovery to a dynamic group of Pods.  ( 7 min )

How I Started When I started my journey with web development, after some weeks I kept hearing about "requests" and "responses." Wait! What is a request? What is a response? Why does HTTP exist, and why is it called HTTP? I hate pretending to understand something. Therefore, I decided to build my own HTTP server—or at least pretend to :). Eventually, I got to the core idea: HTTP is just Hypertext Transfer Protocol—basically a set of rules for transferring data. But what really mattered was understanding that HTTP is built on top of TCP(Transmission Control Protocol), which I'll explain below. So, I started building my own http-server-ts. I asked my friend who had built his own server, and I was genuinely impressed. When I asked him how I could learn all this stuff related to web developme…  ( 10 min )

Everyone's talking about Google's Gemini 3.0, but the real opportunity isn't model vs model—it’s how UI understanding will reshape your daily work. Most teams will wait for the press release. The smart ones will run small pilots inside tools they already use. Here’s the play that actually works ↓ Debates about AI supremacy miss the point. What matters is time to value in real workflows. If an AI can read screens, understand buttons, and learn from short videos, you get stacked gains. Those gains spread across support, ops, sales, and product. For example, imagine onboarding that watches a 3-minute demo and builds a step-by-step checklist from your UI. A support rep could review a screen recording, suggest next clicks, and draft a reply in seconds. In a two-week test, you could aim for 20–30% faster closes and fewer escalations by measuring time, clicks, and accuracy. ↓ Pilot playbook to test now • Pick one workflow with a clear start and finish. • Capture 5–10 real sessions as short videos and screenshots. • Define success before you start: time saved, clicks reduced, accuracy. • Run side-by-side for two weeks: human-only vs AI-assisted. ↳ Document what the AI gets wrong, then simplify prompts or the UI. → Share one clip and one metric with leadership. ⚡ You’ll quickly notice fewer clicks, faster cycles, and cleaner handoffs. ⚡ Leaders get clearer reports, reps get fewer tabs, customers get faster answers. The model matters, but the workflow is the hero. What’s stopping you from piloting this in the next 14 days?  ( 6 min )

AI Spots Trouble Before Traffic Does: Preventing Urban Gridlock with Smart Vision \Imagine a city where traffic jams vanish almost as soon as they appear. No more endless queues, no more wasted time, just smooth, efficient movement. What if AI could predict and prevent traffic disasters before they happen? We've developed a novel technique to identify critical infrastructure anomalies in real-time using a hybrid AI approach. This involves processing video feeds with a two-stage system: first, extracting key visual features; second, using a specialized neural network to rapidly classify the situation as normal or anomalous.

There are chapters in Scripture that comfort us, chapters that challenge us, and chapters that feel like they take a lamp and shine it directly into the deepest corners of the human heart. Gospel of John Chapter 9 does more than that. It doesn’t just illuminate—it exposes. It reveals. It unwraps layers of pride, doubt, legalism, fear, and misplaced certainty. It asks questions we avoid. It brings our assumptions to the surface. It confronts us gently and directly all at once. This chapter is one of those rare places in the Bible where the miracle itself seems almost secondary because the meaning behind it is so piercing. Jesus heals a man blind from birth—but the real miracle in this story isn’t just the restoration of physical sight. It’s the revelation of spiritual blindness in the peopl…  ( 11 min )

Governance refers to the framework of principles, policies, and processes that determine how your organization's cloud resources are administered, kept secure, and optimized. It is the structure necessary to ensure that the environment aligns with your business objectives, security requirements, and compliance obligations. Effective governance is not about stifling innovation. It is establishing guardrails to enable teams to move fast, yet in compliance with organizational standards. Consider it as setting the rules of the highway to ensure safe and efficient transportation, not building roadblocks. Governance without FinOps leads to control without clarity Governance in the cloud ensures control, security, compliance, and accountability. FinOps ensures financial visibility, cost ownership, and optimization. In cloud environments, the cost is not only a finance issue, but it's a governance issue. Governance without FinOps is incomplete. What Happens Without FinOps Teams over spend with no accountability Budgets blow up unexpectedly Business units bypass policies for faster delivery Finance cannot track or justify cloud spending Leadership loses visibility into ROI How FinOps Strengthens Cloud Governance Compulsory tagging policies for allocation This will cost guardrails e.g.) budget alerts, quota limits.

The Control Plane is the “Brain” of Kubernetes. It makes all the decisions in the cluster: What should run? Where should it run? What to do if something breaks? How many replicas should exist? Which node should get which pod? The Control Plane is responsible for managing the entire cluster, while Worker Nodes simply follow its instructions. Why Was the Control Plane Created? Without a central “brain,” you would have chaos: No one decides which node runs which pod No one restarts pods when they crash No one performs scaling No one stores the desired state No communication between nodes Kubernetes needed a central orchestrator. → That is the Control Plane.

In a recent job working with Java and Spring Boot, I found myself second-guessing many of my decisions. Sometimes I would say, “I’m following the project’s patterns.” Other times I realized I didn’t fully master some libraries, specific approaches, or certain uses of annotations. My tech lead had far more experience with that stack than I had. Inevitably, I compared my knowledge level to his. Still, there were several moments when I proposed improvements and delivered solutions that made development and maintenance easier. I worked at that company for almost two years and made several meaningful contributions to the same project. I helped introduce coding patterns that improved the development experience, and I also worked as a full-stack developer on multiple initiatives, including one of the most relevant projects: a chatbot where a colleague and I developed the frontend together. During my time there, I worked on backend systems using Java, TypeScript, Stencil, and other related technologies. I also helped plan and establish a migration process for legacy Java projects, updating framework versions and addressing security issues in outdated dependencies. Even so, a nagging feeling crept in: “Am I way below what they expected? Am I really that bad?” That inner voice was the classic Impostor Syndrome. It had been more than four years since I last worked with Java and Spring Boot. During that time I adapted to the technologies each company used. That constant adaptation has a price: you drift away from certain stacks and lose depth in them. Here’s the lesson I took from that experience — simple yet powerful: Relearning and refreshing your skills is essential. Even if you already have experience, continuous learning is what keeps you confident and relevant. Impostor Syndrome may show up, but it can also be a sign of humility and awareness that there is always room for growth. In the end, what matters most is this: keep learning, keep contributing, and allow yourself to evolve.  ( 7 min )

When Every App Uses AI, What Makes Yours Different? Jaideep Parashar ・ Nov 27 #ai #learngoogleaistudio #api #powerapps  ( 7 min )

We’re living in a strange moment in tech history. Just a few years ago, adding “AI-powered” to your product was a competitive advantage. Every app uses AI: note-taking apps writing tools coding assistants task managers CRM platforms design tools search apps customer support bots Everyone has the same models, the same APIs, the same features, and the same demos. So the real question becomes: When every app uses AI… what actually makes yours different? This is the part most founders and developers get wrong because the answer has nothing to do with models, and everything to do with judgment, workflow, and experience. Let’s break it down. 1. AI Is No Longer a Feature: It’s Infrastructure Five years ago, “AI” was a differentiator. Just like: electricity cloud computing storage databases APIs A…  ( 11 min )

1. The Disintegration of the God Model The history of enterprise computing is effectively a history of the pendulum swing between centralization and disintegration. To understand the current architectural pivot toward the Model Context Protocol (MCP), Agent-to-Agent (A2A) frameworks, and Agent Communication Protocols (ACP), one must first situate these technologies within the broader timeline of integration. We are witnessing the end of the "God Model" era in Generative AI—a brief period where the industry hallucinated that a single, monolithic set of parameters could serve as the universal operating system for all human knowledge and execution—and the beginning of the "Agentic Mesh." This transition mirrors the shift from the mainframe to the client-server model, and later, from the mon…  ( 12 min )

If there’s one thing I’ve learned during my career it’s this: friendships at work are far more valuable than mere professional contacts. They can open doors you never imagined — even if you are living in a different country, adapting to new environments or building your career from scratch somewhere else. At different stages in my journey these connections changed my path. In college, a classmate who ran a company invited me to work with him. Years later, a professor who recognized my technical skills recommended me for a role at a very well-known company in Brazil. Later still, at a company where I built deep friendships, I experienced one of the periods when I learned the most in my career. We had an extremely technical team, and together, we built incredible things. I still keep in touc…  ( 8 min )

Developers should stop wasting time debating whether AI-generated code is “good” or “bad” and start focusing on how to use it intelligently and responsibly. AI does not replace technical knowledge or engineering experience. What it does is act as a high-leverage tool that expands your ability to deliver, explore, validate and learn. When used with proper supervision, AI becomes a powerful ally rather than a threat. AI can accelerate your work in multiple ways. It can help you understand unfamiliar code patterns, explore different implementation strategies, and create examples that serve as a starting point for your own solution. Imagine you need to maintain a legacy Angular application and have no idea how to write a unit test for a specific scenario. You can ask AI for an example in a sim…  ( 7 min )

There are chapters in Scripture that sit quietly on the page until your life finally reaches the moment where you can hear them. Chapters that wait for your wounds to be open enough, your heart to be honest enough, and your spirit to be tired enough that the words stop sounding like history and start sounding like rescue. That is the power of John 8, the chapter where Jesus doesn’t just teach truth — He embodies it. This is a chapter that exposes every part of the human condition: shame, pride, self-righteousness, sin, truth, hypocrisy, fear, compassion, and the relentless mercy of God. And when read with an open heart, this chapter will do for you exactly what Jesus did for the woman caught in adultery: This article is written the way a legacy article should be — slow, deep, personal, spi…  ( 12 min )

Time to complete: 30-60 minutes Difficulty: Intermediate Skills tested: Application Security, Algorithm Design, Edge Case Handling In April 2020, security researcher Tom Anthony discovered he could crack into any password-protected Zoom meeting in under 3 minutes. The flaw? No rate limiting on password attempts combined with Zoom's default 6-digit numeric passwords meant attackers could brute-force all 1 million possible combinations within minutes using basic Python code and a handful of cloud servers. Zoom immediately took down their web client on April 2nd to fix the vulnerability, but the damage was done—during peak pandemic lockdown, when millions relied on Zoom for private business meetings, therapy sessions, and confidential legal consultations.

Unlocking Data Narratives: Visualizing Information Flow with Concept Graphs Drowning in data but struggling to see the big picture? Do you find it challenging to translate complex data streams into actionable insights? Imagine being able to visualize the underlying logic of your data, revealing hidden patterns and enabling you to build intuitive conceptual models. Concept graphs offer a powerful solution. They are essentially visual blueprints of data processes, representing how data flows and transforms through a system. These graphs are structured as directed networks where nodes represent data states or processes, and edges indicate the flow of information between them. Think of it like a street map for your data – each intersection represents a key transformation, and the roads illus…  ( 7 min )

Confluent is the name of a company that provides commercial support for Kafka. When enterprises use open source software, they often look for product support on the basis of payment. For example if the software has bugs or security issues, enterprises need tech support in a time bound manner. Confluent is one of the companies that provide such support. Kafka is a stream processing framework. There are many of them out there, both proprietary and open-source. Kafka is popular because it’s open-source, highly performant and flexible. I’m not going to go into lengthy comparisons with other frameworks. Instead, I’ll try to explain why you should use stream processing in the first place. Why stream processing?

Line ending inconsistencies between Windows and Linux systems cause formatting issues, Git warnings, and script failures. Operating systems use different conventions to mark the end of a line in text files, creating compatibility challenges in cross-platform development: Windows: Carriage Return + Line Feed (\r\n or CRLF, hex 0D 0A) Linux/Unix: Line Feed only (\n or LF, hex 0A) Classic Mac OS: Carriage Return only (\r or CR, hex 0D) This historical difference stems from typewriter mechanics. Windows inherited the CRLF convention from DOS, which maintained compatibility with teletype machines that required both a carriage return (move to line start) and line feed (advance paper). Bash scripts with Windows line endings fail with cryptic errors: bash: ./script.sh: /bin/bash^M: bad interpreter…  ( 13 min )

TL;DR: AI-First vs. Digitally-Enhanced 5 Key Messages 88% use AI. 39% see impact. Most are "Digitally-Enhanced" (10-15% gains). AI-First delivers 34x revenue per employee via complete process redesign, not tool adoption. Mindset is the bottleneck. Shift from certainty → curiosity, mastery → learning, competition → collaboration. Organizational debt (silos, risk-aversion) must be paid down alongside technical debt. High performers optimize tempo, not cost. Elite 6% complete Scan-Orient-Decide-Act in 2 weeks vs. 8. Velocity compounds. Decision speed = competitive moat. Pilot purgatory is real.

On November 18th, AWS introduced new flat‑rate pricing plans for Amazon CloudFront designed to make content delivery and security costs more predictable for teams of all sizes. These plans sit alongside the existing pay‑as‑you‑go model and bundle multiple services into a single monthly price per distribution. Traditionally, CloudFront has used pay‑as‑you‑go pricing, which is great for starting at $0, scaling with actual usage, and only paying for what you consume. The tradeoff is that estimating costs can be difficult, especially when you also depend on AWS WAF, DDoS protection, Route 53, CloudWatch Logs, and S3 for a single application. You end up stitching together multiple pricing pages and trying to map them to your traffic patterns just to get a reasonable forecast of your monthly bil…  ( 8 min )

JSON, You Talk Too Much: Exploring TOON for Token-Efficient LLM Communication Introduction JSON, buddy, you might be a bit too chatty. As developers, JSON (JavaScript Object Notation) is like the air we breathe. It's everywhere—API responses, config files, logs, you name it. I've trusted JSON as my reliable companion for years. But ever since I started working with LLMs (Large Language Models), something's been bugging me: "Wait... are you talking way too much?"

Author: (bnggbn) Context: Building on IRP In my previous articles, I established two foundational concepts: IRP (Inverse Responsibility Principle): The backend defines semantics; the frontend must normalize them.

Where do "semantics" come from, and how do clients transform messy AI and human intent into backend-consumable meaning?

I recently completed a project where I built both resilient and non-resilient cloud resources using Terraform to test a cloud resilience monitoring tool that's still under construction. The objective was to calculate the Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for individual cloud resources, with the proof of concept being done on Azure. As an AWS-native DevOps engineer, I had to get familiar with Azure fast. I took a 10-hour Udemy course and dove straight into provisioning infrastructure-as-code. It was my responsibility to set up all the resources, and that meant learning a completely new cloud platform while implementing disaster recovery solutions that actually work. The main differentiators between resilient and non-resilient resources came down to two things:…  ( 10 min )

Hi DEV Community! 👋 This is my first post here, so I wanted to share a bit about my learning journey as a developer. How I Started I started learning Java because I wanted to build real applications and understand backend development properly. My first steps were simple: Learning core Java concepts Understanding OOP Practicing small programs Trying to fix errors without giving up After gaining some confidence, I moved to Spring Boot, and that completely changed the game for me. Why Spring Boot? Because it makes backend development clean, fast, and professional: Easy API creation Built-in security options Great documentation Used by most companies I first built small APIs like: User registration Login system Simple CRUD JWT authentication These small wins helped me stay motivated. What I’m Learning Now Right now I’m learning: Spring Security JWT Authentication Multi-tenant architecture React & Next.js for frontend Building full-stack projects My goal is to become really strong in backend (Java + Spring Boot) and build complete systems end-to-end. Why I Joined DEV I want to: Share my learning journey Write simple explanations for other beginners Connect with developers who love backend and frontend technologies Start contributing to open-source projects  ( 6 min )

Welcome. I am a 13 year old litrature freak and tech enthusiast. While I have been experementing with robotics and basic programming since I was 9, I have decided to properly learn Python. I will be posting weekly reports on what I learnt that week as well as if I did/am doing any significant projects. This is mostly so that I can hold myself accountable but feel free to use my reports to plan out your own python study if you are a beginner like me. I also have an abnormal intrest in the word 'Quantum'. While I do love Shakespere and old Gothic litrature, I also love the consept of the multiverse, time bending and how Quantum Computing can be related to it all. So, I will be trying to learn about topics surrounding the word and reiterate whatever I understood here. Aside from that, I also love ethical hacking and have previously taken part in a few basic hackathons. I wish to deepen my sills and understanding in this area after I have finished learning a good level of python. Have a great day.  ( 6 min )

Hexagonal Architecture is very popular these days. However, I have seen that a lot of the resources out there that try to teach it do so in a very abstract and technical way. While that is great for understanding all the details, it makes for a poor introduction. So, in this article, I would like to address this issue. I would like to make a simple and straightforward introduction to HA (Hexagonal Architecture) and give you some other resources for further learning, including a public repo that applies HA that I created for this article. So let's begin! Hexagonal Architecture is a design paradigm that focuses on separating the core of the application from everything else and specifying rules on how these two parts should interact.

Semantic Object Factory: The Missing Layer That Aligns AI Intent With Backend Semantics Author: bnggbn For the last two articles, we established two major ideas: IRP — the backend defines semantics; the frontend normalizes them. The frontend is now the semantic boundary, not just a UI renderer. If you missed the first part, IRP established that: the backend defines semantics, and the frontend must normalize them. Today, we address the hard question of how the frontend achieves this normalization. But a critical question emerges: Where do “semantics” actually come from? And how do clients normalize messy AI/human intent into them?

Introduction The workflow for an agentic app starts when the user interacts with it by presenting a prompt through a chat interface or form. The agent gets this prompt and analyzes it as to what the user intends and requires. It can take the help of LLM to acquire tasks, clarify the details, and break the whole into subtasks. As soon as the agent has a clear understanding of the target, it selects the most appropriate specialized tools or services to achieve the goal. These bring APIs, databases, generative AI (for writing, image generation, etc.), or other partnered systems, and the agent might arrange or put together multiple tool actions dependent on the difficulty of the job. The agent continually assesses and alters, carrying out the tool calls again and asking for more clarificatio…  ( 11 min )

In JavaScript, this is perfectly valid: class Animal { move() { console.log("Moving..."); } } class Dog extends Animal { bark() { console.log("Woof!"); } } But what if we want Dog to also inherit from a Swimmer class? JavaScript says "no way." We're stuck with a single inheritance chain, which can feel restrictive when building complex applications.

Most React or frontend projects start with something like: src/ components/ hooks/ utils/ pages/ context/ styles/ This works… until it doesn’t. As your project grows, you start jumping between folders just to work on a single feature. A simple update may require touching multiple directories. Files become harder to discover, boundaries blur, and the struct…  ( 7 min )

I built a tool for devs who are tired of babysitting SMTP and deliverability every time they ship a new app or spin up a small SaaS: SMTP Zen. It’s a transactional email + standard mailbox service aimed at developers, freelancers and domain investors who just want stuff to land in the inbox and move on with their lives. What it does: Unlimited domains & mailboxes – No “seats”. Add as many domains/mailboxes as you need and forget about artificial limits. SMTP that actually lands – Guided SPF/DKIM/DMARC setup and enforced TLS so you don’t have to become an email wizard to stay out of spam. Simple sending & forwarding – Custom domains, per-client aliases and mailbox-free forwarders. Great for spinning up project/client addresses in seconds. Real-time logs – Full send/receive paths and errors for every message so debugging deliverability isn’t a guessing game. Zero-downtime IMAP migration – IMAP sync with automatic delta sync, so you can move existing mailboxes without scary cutovers. Usable webmail & dashboard – Fast webmail (Crossbox) with unified inbox, calendar and contacts, plus a clean panel for domains, DNS, mailboxes, forwarders, logs and billing. As a launch promo I set up a 20% off coupon (valid until Dec 31): ZENLAUNCH If you’re curious or want to tear it apart, you can check it out here: SMTP Zen  ( 6 min )

We’ve all had those fuzzy ideas: “Wouldn’t it be fun to make a simple swipe-or-click game?” Usually, that thought dies somewhere between opening a blank repo and realizing you don’t have art, sound, or time. This time, I didn’t let it die. I opened up Gemini Studio AI (free version, nothing paid) and threw in a prompt: “I want to develop a simple yet relatable and fun game. Fuzzy concept is mobile swipe or click type game.” And off we went. The first draft was rough — ugly, basic, but it worked. I played for a few minutes, scribbled notes in the chat box, refined my prompt, and waited. Rinse, repeat. That loop was surprisingly engaging. Instead of grinding through code, I was iterating on ideas. Things that would normally take me a week were happening in two minutes. I sketched out…  ( 7 min )

Python for Absolute Beginners A Complete, Practical Guide Before You Even Start Coding Most people start learning Python by copying short snippets like: print("Hello, world!") They run the code, see the output, feel good, and… they learn nothing. Real learning happens when you understand the foundations behind the syntax — the concepts that turn a beginner into a real programmer. This guide does exactly that: it builds your foundations through clear explanations and practical examples, including a real micro-project you can extend. Is (and Why It Matters) Python is: high-level → you focus on ideas, not memory interpreted → runs code line-by-line dynamically typed → no type declarations general purpose → used by AI, web dev, automation, analytics, DevOps The design…  ( 9 min )

I'll never forget the moment I realized my wallet was becoming obsolete. I was standing in a busy coffee shop, my hands full with my laptop bag and a dripping umbrella. When it came time to pay, I had to perform an awkward juggling act—balancing everything while fumbling for my wallet, then struggling to tap my phone. The person behind me sighed loudly. That’s when it hit me: why are we still carrying separate devices in 2025? This personal frustration led me down a rabbit hole of research and a unique opportunity to test a prototype that most people think is science fiction. By 2026, your clothing won't just be smart—it will be your wallet, your ID, and your digital identity. Here’s what I learned from a week of living in the future.

In 1776, Thomas Jefferson drafted the Declaration of Independence. In 2025, AI detectors flagged it as 99% machine-written. That’s not a metaphor. That’s a documented failure. ZeroGPT and OpenAI’s own detection tools labeled the Declaration—a document written nearly 250 years before large language models existed—as AI-generated. Not borderline. Not “maybe.” But with 97–99% confidence. And it’s not just the Declaration. The 1836 Texas Declaration of Independence? 86.54% AI. The U.S. Constitution? AI. The Book of Genesis? AI. These tools don’t know what a human is. They don’t know what a machine is. They only know statistical patterns—and they’ve been trained on the very tradition of excellent human writing they now penalize. I’ve Lived This I’ve published six cybersecurity books.

Hi everyone! In this article I wanna show you 2 options to install and run the cursor CLI on a Windows O.S (both require WSL2 + linux distro like ubuntu) for .NET developers (but you can use it for other stacks as well, just adapt it): Everything including git and repositories within the linux distro (better performance but greater overhead to setup) Just the Cursor CLI within the linux distro (easier, performance overhead just for the Cursor CLI) Here you'll also learn how to setup the terminal within the Visual Studio 2022+ to use the Cursor CLI (or others tools). We won't focus on details like how to setup WSL2 + linux distro, neither install the git, you can google it. I know you can. Note: I'll consider you have the WSL2 already set up!

If you've ever tried building a Web3 product, you know the pain: the wallet is often the single most complex, expensive, and risky component. Developing your own wallet isn’t a “small module” — it's effectively a standalone product with its own infrastructure, logic, security requirements, and UX challenges: key management, seed phrase handling, secure signing, multi-chain support, device binding, recovery flows, backend maintenance, chain upgrades… it goes on. Handling all that reliably can consume months of development work and a significant portion of your budget. That’s where Wallet-as-a-Service (WaaS) comes in — and why it’s quickly becoming the “Firebase for Web3.” WaaS abstracts away most of the complexity, allowing teams to focus on building product features instead of wrestling wi…  ( 8 min )

I've been using AI coding assistants for about 8 months now. Cursor, GitHub Copilot, the usual suspects. hey're all impressive, but they share one fatal flaw that's been driving me insane: They forget everything. You explain your project architecture. The AI generates some code. Five minutes later, you're explaining the same architecture again. Every session starts from scratch. Every feature request requires re-explaining your context. I found myself maintaining a text file of prompts to copy-paste at the start of each session: "We use Zustand for state management, not Redux" "All API calls go through our custom fetcher with retry logic" "Components follow the compound component pattern" "Test files go in __tests__ not next to the component" I was spending 10% of my coding time just expl…  ( 11 min )

When it comes to infrastructure as code, tools like Terraform, AWS CDK, and Pulumi immediately come to mind. Although these tools include testing capabilities, they often lack a fully integrated local simulation environment that accurately mimics cloud behavior. This gap can lead to longer, more expensive iteration cycles during development. Winglang addresses this challenge by providing a local simulator that mimics cloud behavior, enabling developers to test their code locally before deploying it to the cloud. Additionally, its simple and intuitive syntax and concept of preflight (static infrastructure code) and inflight (the application logic) code makes it easy for developers to work with cloud resources, regardless of their level of experience.

The Takeaway / TLDR AI-First DevOps is not just an evolutionary step in software engineering—it’s a revolutionary shift in how we build, scale, and manage digital systems. The companies and teams that thrive won’t be those who simply bolt on AI add-ons, but those who fundamentally reimagine their workflows, culture, and infrastructure from the ground up, trusting in intelligent automation to unlock exponential gains. This moment demands more than tool adoption; it calls for a reinvention of roles, priorities, and even the web itself. The future belongs to those bold enough to embrace the autonomy and partnership AI offers, while building the guardrails and documentation that allow trust to flourish. The real risk isn’t being replaced by AI, but missing the race because you hesitated at …  ( 18 min )

Launching a SaaS as an engineer feels exciting and terrifying at the same time. You probably have a brilliant product idea but freeze when it comes to the business side. You've built something amazing in your spare time, maybe solved a problem that's been bugging you for months. The hard part usually isn’t the code — it’s everything around it. The first step is defining the problem in painfully simple language. If you can’t explain what your product does in one sentence to a non‑technical friend, it’s going to be 10x harder to explain it to a potential user. Skip the buzzwords and nail the “who, what, why”: who it’s for, what it does, and why it matters. Next, build the absolute smallest version of the product that still solves the core problem. Not a “tiny version of your big vision,” but…  ( 7 min )

The Icon Problem We've All Faced Picture this: You're building a React app, and you need icons. Simple enough, right? Wrong. You start with react-icons, and suddenly your bundle size balloons to 2MB+. You switch to icon fonts, but they feel like using a fax machine in 2025. You try Iconify's web components, but oops—your app breaks offline. And don't even get me started on manually copying SVGs from different icon libraries and trying to maintain them. 🤯 Today, I want to introduce you to Iconx—a CLI tool that fundamentally changes how we work with icons in React.

More snow = more fun, but I have to be aware that I cannot simply get up and go. Someone has to shovel out the driveway and scrape off the car. Tired of constantly refreshing weather websites, I decided to automate the whole process.

So, you are a frontend developer and you receive some Figma designs from a client, along with a clear plan for building the UI. Then, a few minutes into turning these designs into code, the complexity begins to surface, as handling variations of components, styling, and other interactivity of the design becomes apparent. In addition to the time and effort, this can be a big challenge for developers. However, turning complex Figma designs into clean and responsive code without worrying about these challenges is becoming a thing of the past.

I work in e-commerce and SEO by day, so I spend a lot of time dealing with complex stacks, databases, and user tracking. But when I wanted to build a simple tool to track my own subscription spending, I didn't want any of that. I didn't want a database. I didn't want user accounts.

I’ve been spending the last few weeks heads-down on a new project, and I’m finally at a point where I can share what I’ve been building. I realized that while there are plenty of templates out there, it’s hard to find one that combines a clean, futuristic UI with solid, scalable code. So I decided to make my own. I’m calling it Krome (for now), and it’s a high-performance landing page + multipage template built for AI startups and modern SaaS platforms. Link: https://ai-agent-template-tan.vercel.app/ My goal with this template was simple: create a UI that immediately feels trustworthy and premium. Think deep dark mode, soft glowing gradients, glassmorphism touches, and bento-style feature blocks. I spent a lot of time refining the Pricing and Feature sections to make sure the visuals guide the user naturally through the product journey. This isn’t just a pretty UI—it's built to scale. Some of the core features include: Multi-theme support: Easily switch accent colors or entire theme presets. ** Multi-page architecture:** Includes more than just a landing page—About, Contact, Sign Up, and more. Fully working MDX blog: Write posts in Markdown and have them render beautifully. Dynamic SEO: Every page and blog post automatically gets proper metadata. The project is about 80% complete. Most of the core pages, UI sections, and responsive layouts are done. The remaining work is mostly polish: Making animations (especially scroll reveal) smoother. Improving the mobile experience. Cleaning up code comments and simplifying components so it’s easy for anyone to customize. If you want to check it out or share feedback, the link is above. Still polishing things, but it's getting close!  ( 7 min )

So I finally watched AlphaGo, that documentary about the Google DeepMind AI that took on the world champion in Go, and honestly… I didn’t expect to enjoy it this much. I thought it would be one of those “tech bros hype themselves” films, but wueh, it’s actually deep. First things first,the game itself. Go is like chess on steroids. Watching those pros talk about it felt like watching athletes explaining how they breathe. The amount of strategy, intuition, and reading the board… it made me respect the game a lot more. And the way the documentary broke it down for normal people? Lovely. Even those of us who have never touched a Go board can follow the tension. Then there's Lee Sedol.

Introduction Why Must We Write Clean Code? To answer this question, let me tell you A story mentioned in the book "Clean Code" by the author In the late 80s, a killer app was written. It was very popular, and lots of professionals bought and used it. But then the release cycles began to stretch. Bugs were not repaired from one release to the next. In short, writing code that is difficult to read and understand clearly makes it hard for other programmers to understand and modify the code. So, if you want to write clean code to help your staff work without any question mark, like what this code does and what its meaning is, you can follow a series of Clean Code that comprises many chapters, and every chapter will contain some guidelines that help you to write clean code.

I’ve tested hundreds of viral ChatGPT prompts. Most? Overpromise and underdeliver — they sound clever but produce generic, robotic replies. I don’t want “viral.” I want useful. After months of experimenting, I collected 5 prompts people share because they genuinely work. No jargon. No gimmicks. Just smart ways to save time, think clearly, and get unstuck. Try this: Why it works: It forces clarity. ChatGPT drops jargon and gets to the core idea. Example: “Quantum computing is like reading every book in the library at once instead of one by one.” Use when: researching anything confusing (taxes, AI, LLMs, mortgages). Try this: Why it works: It forces healthy disagreement and exposes blind spots. Try this: Why it works: Using the word “unexpected” avoids generic answers. You get fresh takes like: “How fast fashion algorithms manipulate trends” “The carbon cost of organic cotton” “Why renting clothes often fails” Try this: Why it works: We all write fuzzy first drafts. This sharpens them instantly. Before: “I was wondering if maybe you could possibly review this document when you have a moment?” After: “Could you review this document by Friday?” Try this: Why it works: “Act as a [role]” activates domain-specific feedback — not generic proofreading. Prompts are starting points. To get great results: Bad: “Fix this.” Good: “Fix this LinkedIn post. Make it punchier and remove passive voice.” “Under 50 words” “Only bullet points” “Three options” If it sounds robotic: “Make it more casual, like a friend explaining.” Reusable templates like: The best prompts solve your specific problem. Example I used last week: “SEO is like putting up signs for your bakery. The better your signs (your website content), the more people Google sends to your door.” Perfect. Pick one prompt from above.

Think of it as Hapi, but with: Type safety throughout Messaging support (Kafka-ready) Auto-generated OpenAPI & Postman docs Built-in logging via Winston So not "Yet again a new Nodejs framework this year!" in case your were thinking that (I know you did) but rather a practical evolution: the same trusted Hapi core, now supercharged. It’s about cutting boil…  ( 7 min )

Or: How I Learned to Stop Worrying and Love SERIALIZABLE Tags: #postgresql #database #concurrency #debugging You know that feeling when your code is perfect, your tests are green, but production still betrays you? It's 3 AM. Our e-commerce platform just sold the same limited-edition sneaker to 47 different people. We only had 12 pairs. The interesting part? “enough stock available.” And somehow, we oversold by 350%. async function purchaseItem(itemId, quantity) { const available = await db.query( 'SELECT stock FROM inventory WHERE id = $1', [itemId] ); if (available.rows[0].stock >= quantity) { await db.query( 'UPDATE inventory SET stock = stock - $1 WHERE id = $2', [quantity, itemId] ); return { success: true }; } return { success: false, erro…  ( 7 min )

Many enterprises rely on AWS S3 as the backbone of their data storage strategy because of its immense scalability, global reach, and extreme durability measured in eleven nines. Everything from audit logs and backups to machine learning datasets often ends up living on S3. But S3 is not a file a system, it’s an object store—an important difference. This means that S3 wasn’t designed to handle low-latency, high-frequency access or POSIX-style workloads. It’s missing crucial file system features like atomic renames, file locking, shared caching, and sub-millisecond response times. Even though it’s a common practice, treating S3 like a traditional file system often leads to performance bottlenecks, unpredictable behavior, and the need for engineering workarounds. As data volumes increase and …  ( 12 min )

Hello there! If you've ever felt overwhelmed by the idea of securing a microservices architecture, you are not alone. It's a common stumbling block. In a monolithic app, you just check the session in one place. But when you have 5, 10, or 50 services, how do you make sure only the right people get in? Today, we're going to build a robust, production-ready authentication flow using Node.js. We'll use a pattern that is both scalable and easy to understand: Gateway Authentication and Service-Level Authorization. By the end of this tutorial, you'll have a working system with 3 services: API Gateway: The entry point (The Bouncer). Auth Service: Handles Login (The ID Issuer). Custom Service: A demo service with Public, User, and Admin routes. Let's dive in! Before we write code, let's visuali…  ( 9 min )

A few months ago, all of your startup’s data could be stored in just one database. Now, you’re overwhelmed by customer data from six separate services, and your operations team is requesting detailed analytics. Relying on manual data queries to the production database is no longer feasible, and with your engineering team already at capacity, you need a specialized layer that can deliver insights without disrupting your customer-facing production systems. Nowadays, businesses produce data from all directions: user interactions, logs, third-party tools, and more. To generate meaningful business insights, you need data—and as such, your data architecture shapes what you can analyze. Production databases, designed for user operations, aren’t built to handle the complex queries needed for in-de…  ( 11 min )

After a decade training Nuxeo developers, I can predict when someone quits: Day three. They're drowning in diagrams trying to understand document models, schemas, facets, repositories, event buses, lifecycle states, automation chains... What I wish someone told me in 2013: Don't try to understand Nuxeo's architecture first. Start with OSGi concepts and solid Java. Everything becomes logical after that. Real prerequisites: Java 11/17/21 (solid skills, not "took a class once") OSGi concepts (bundle lifecycle, service registry, extension points) REST API mastery Polymer 3.x (if touching UI) Common pitfalls: Trying to understand everything before coding Ignoring OSGi (then weird classloading errors) Fighting the platform vs learning its patterns Using Java for stuff Studio generates in minutes Not reading logs (they're helpful!)

Working in hospital theatre recovery has taught me the importance of precision, adaptability, and reliable systems. Beyond patient care, I’ve also been closely involved with managing data, coordinating appointments, and ensuring smooth workflows. The more I worked with these digital systems, the more I realised something bigger was happening around us. Technology, especially AI is reshaping industries at an incredible pace. I began to see how automation, cloud solutions, and smart data systems are becoming the backbone of modern healthcare and beyond. That shift changed my perspective. I didn’t just want to use these systems. I want to understand and contribute to the technology driving them. This curiosity led me into data analysis, then data engineering, where I explored how information flows and how insights are created. Each step opened a new path and ultimately guided me toward Cloud Engineering and DevOps. The foundations that power AI, automation, and scalable digital systems. Balancing a full time healthcare role with learning tech hasn’t always been easy, but it has been rewarding. For me, this transition is about embracing change, staying future ready, and being part of the innovations that are reshaping our world. I’ll be sharing my journey. The lessons, challenges, and small wins along the way. If you’re also navigating a career transition or exploring the cloud/AI space, I’d love to connect and grow together.  ( 6 min )

Day 1 — Trying to get the QEMU kernel sandbox going Time to setup the environment for kernel development. Rather than risk shooting myself in the foot on my bare host, I decided to: build a custom kernel + minimal user land, and boot it inside QEMU. What I thought would be a straightforward path — went somewhat astray, or at least was different than what I'd expected it would be. Clone a recent upstream Linux kernel source tree. Installed dependencies (compiler, build tools, kernel-dev libs, etc.). Configure the kernel (make defconfig), enabled built-in drivers I expected to need (make kvm_guest.config). Which the built in configs for kvm was nice to find instead of having to menuconfig and change them all myself, or write config snippets and merge them with merge_config Built a minimal root filesystem using BusyBox + a tiny initramfs / minimal userland. This provided a good refresher of how booting the kernel works. Launched QEMU: point it to the kernel image, attach the rootfs, set console/serial, etc. A quick "hello world" environment. Boot → get a kernel log on serial → minimal root shell → experiment with loading modules / tinkering / debugging — all safely sandboxed, without risking my host’s stability. What followed was… a lot of head-scratching. Mostly I spent a ton of time digging through forums and reading posts about how the systems worked, but it really wasn't all that bad. Starting with some kernel panics as init wasn't built properly or I was pointing to the wrong bzImage. Once I got all the pieces properly laid out it all worked perfectly. A nice safe environment where I don't have to worry about crashing my daily driver. Build and test a trivial kernel module, load it, unload it.  ( 6 min )

The Challenge Black Friday is coming in 8 weeks, and your payment platform needs to handle a massive traffic spike: Normal load: 500 transactions/second Expected peak: 5,000 transactions/second (10x increase!) Current capacity: Only 1,500 transactions/second Budget constraint: Minimize costs and auto-scale down after the event Requirement: Zero impact on current service levels during preparation This isn't just about adding more servers. It requires a comprehensive scaling strategy across the entire stack: application layer, database, caching, networking, and monitoring. In this article, I'll walk through a complete AWS-based scaling strategy that handles the 10x traffic spike while optimizing costs and maintaining security and compliance.

As you embark on your journey into Infrastructure as Code (IaC), understanding how to translate simple resource needs into code is the essential first step. Terraform enables us to define infrastructure, ensuring consistency and efficiency. This blog post walks through the process of provisioning the simplest possible resource on AWS: an S3 bucket, leveraging the core Terraform workflow. To begin provisioning any resource, you must first define your configuration in a file that uses the .tf extension (e.g., main.tf). Terraform recognizes this extension as a configuration file. For our task creating an S3 bucket, we consult the Terraform documentation to find the required resource type: aws_s3_bucket. Code Example: Defining the S3 Bucket internal name (e.g., firstbucket), which is used to …  ( 8 min )

Sean Fennessey and Amanda Dobbins wrap up their yearlong countdown by landing Spike Lee’s 2002 drama 25th Hour at No. 3, praising it as an under-appreciated masterpiece that lives and breathes in real time. They unpack Lee’s bold stylistic choices—everything from the kinetic camera work to the razor-sharp dialogue—that make the film feel urgent, intimate, and emotionally gut-wrenching. Beyond its tense narrative of a man’s last day of freedom, the hosts highlight the movie’s “fricative tension,” the way every idea and interaction crackles with unsaid conflict. Whether you’re streaming on Prime or catching it for the first time, they argue, 25th Hour remains one of the century’s most affecting cinematic experiences. Watch on YouTube  ( 6 min )

🚀 Learn LangChain JS (with LangGraph) — My Open-Source Repo Over the last few weeks, I’ve been learning how real AI backends are built — not just “call an LLM” but actual systems that use tools, memory, RAG, scraping, agents, and workflow logic. While learning, I noticed something: There isn’t a simple, practical, beginner-friendly way to learn LangChain JS + LangGraph with real examples. So I decided to build one myself. 👉 Learn-LangChain (JS) 🔗 Repo: https://github.com/iparesh18/Learn-LangChain ⭐ What’s Inside Prompt chains Output parsing Embeddings + vector search Basic RAG Tools (RunnableLambda + validation) Puppeteer scraping LLM-as-a-tool Agent execution LangGraph (nodes, edges, routing) Multi-agent flows (planner → scrape/search → final answer) Every file is a standalone lesson. 🌱 Why I Built This I wanted something simple, practical, and structured — the kind of resource I wish existed when I started.

There are moments in the Bible that read like history—and then there are moments that read like you. John Chapter 5 is one of those moments. It is not gentle. It is not simple. It does not sit quietly in the corner of Scripture. It confronts you. It exposes you. It comforts you. It awakens you. It speaks to the parts of your life that feel old, tired, worn down, and forgotten by time. It speaks to the cycles you’ve learned to live with, the pain you’ve learned to manage, the disappointment you’ve learned to hide, and the long-term struggles you’ve learned to survive. John 5 is not about a man who needed healing. This chapter is about mercy with muscle. John 5 is the chapter that won’t let you stay the same.

Financial data rarely behaves calmly. Prices spike, plunge, pause, and surge again—often without warning. Traditional time-series models like ARIMA or linear regression help capture patterns and trends, but they assume constant variance. Real markets don’t behave that politely. Their volatility changes constantly, and this “changing variance” itself becomes part of the story. Why ARCH and GARCH? A Gap in Classical Modeling ARCH: The Foundation of Volatility Modeling GARCH: A More Flexible Version of ARCH Volatility Clustering: The Heart of GARCH Understanding GARCH(p, q) If > 1 : volatility explodes (rare in real markets) This tells you how long it takes for a volatility shock to fall by half. Hands-On Implementation in R Step 1: Load the Data We then convert date and day into proper formats: Step 2: Load Supporting Packages library(fGarch) Step 3: Create the Time Series The plot reveals small, persistent fluctuations—perfect for volatility analysis. Step 4: Compute Log Differences (Inflation) The summary reveals heavy variability (range: −2.8 to +5.5), indicating suitability for GARCH. Step 5: Identify ARIMA Structure The spikes suggest an ARIMA(5,0,0) structure. Test residual autocorrelation: A high p-value confirms a good ARIMA fit. Step 6: Fit GARCH(1,1) Check the model: The output will show parameter estimates, residual diagnostics, and persistence.

The Problem I Was About to Create While building my NestJS backend, I almost made a rookie mistake: creating one big PATCH /users/:id endpoint that could update everything about a user—profile info, password, email, account status, role... you name it.

After some research and guidance, I learned about two critical principles: Single Responsibility Principle (SRP) Principle of Least Privilege Let me break down why they matter and how they apply to API design.

A year ago, if you'd asked me how to boost productivity, I'd have given you the standard advice: work harder, multitask better, attend more meetings. Turns out, that's exactly the wrong approach. Real improvement comes from working smarter. Here are three strategies that actually moved the needle for me. We're all drowning in information. Emails, meetings, Slack threads, endless to-do lists. The real productivity killer isn't the work itself – it's trying to remember what happened yesterday, why you made that decision, or where that critical feedback lives. 23 minutes – that's how long it takes to refocus after an interruption This "context drift" destroys more productivity than most people realize.

Stop wasting 15 minutes every morning on status updates. Here's how I built a system that writes my standups automatically—and actually makes them useful. If you're like most developers, your morning standup feels like this: scramble to remember what you did yesterday, mumble something about "working on tickets," promise to finish that PR today, then immediately forget what everyone else said. I used to spend 15 minutes every morning just preparing for a 5-minute standup. Multiply that by 5 days a week, and I was burning over an hour weekly on meeting prep alone.

Hey Devs! 👋 We all know the feeling of those simple, yet frustratingly addictive games where "just one more try" turns into an hour of gameplay. That was exactly my inspiration. I wanted to create something that tests your reflexes to the limit, without complex mechanics or pay-to-win barriers. 🎮 The Concept It sounds easy, but it's all about rhythm and focus. You need to tap the screen continuously to keep your character alive. Tap too slow? Game over. Tap too fast? You might lose your rhythm when obstacles appear. It’s a pure test of endurance and reflexes. ✨ Key Features Infinite Gameplay: There is no end, only your high score. The longer you survive, the harder it gets (progressive difficulty). Free to Play: No hidden purchases or pay-walls to progress. It is 100% skill-based. Detailed Stats: As a dev, I love data.

In the previous chapters we looked at how params and searchParams work in Next 16. We then went over an example that we will be testing and finally setup Jest. We're now all ready to start writing some actual tests. The code for this example is available on github. Our example looks like this And consists of a page.tsx component, a client component for the buttons and a helper function validateSortOrder to validate the searchParams. Let's do this function first. This isn't relevant on this topic but the tests run different scenario's for our searchParams like: {}, { sortOrder: '' }, { sortOrder: 'asc' },... So, we handled this and no longer need to test it. Here is the function: export type SortOrderT = 'asc' | 'desc'; export function validateSortOrder( searchParams: A…  ( 11 min )

‘Two for the Money’ Rewatchables Breakdown Bill Simmons, Chris Ryan and Cousin Sal dive into the wild world of 2005’s sports-betting drama Two for the Money (starring Matthew McConaughey, Al Pacino and Rene Russo), all while placing their own imaginary Monday night parlays. They kick things off with a cold open before analyzing how the movie handles the highs and lows of wagering big, sharing plenty of behind-the-scenes trivia along the way. After hashing out the film’s best betting scenes, the crew picks their single most rewatchable moment and then fires off a rapid-fire “Categories” round to rank everything from standout performances to jaw-dropping plot twists. It’s equal parts film deep-dive and friendly smack talk—perfect for sports-movie junkies. Watch on YouTube  ( 6 min )

Sean Fennessey and Amanda Dobbins keep their 25 Best Movies of the 21st Century series rolling with No. 3: Spike Lee’s 25th Hour.

Everything Wrong With KPop Demon Hunters In 16 Minutes Or Less CinemaSins’ latest roast tears into KPop Demon Hunters, gleefully clocking every over-the-top fight move, cringe-worthy K-pop trope and random product placement. From “demon horde” clichés and shaky CGI to cheesy one-liners set to a catchy soundtrack, no plot hole or camera flip is safe from their trademark snark. After the sins tally, they plug their poll, Patreon and all the socials—Discord, Reddit, TikTok, Instagram—along with a shout-out to their writers team and linktr.ee for more CinemaSins madness.

This is a tech log but my tech gang needs to hear this. People say you can't work without a healthy body. True. What I realized: you also can't workout without actually working, like being productive during the day. If I'm scrolling all day, doing nothing productive, my brain's mush. When I go to the gym with a mush brain, I can't lift properly. The connection isn't there. But when I'm actually working—coding, building, solving problems—my brain's sharp. And when my brain's sharp, my body responds. I lift better. Move better. Everything clicks. It's a loop. Work feeds workout. Workout feeds work. Mess up one side and the whole thing falls apart. "Don't ask me to love myself. You'll be doomed cause I hate everyone once I start loving myself." Been sitting with that one. Not sure if it's tru…  ( 7 min )

INTRODUCTION If you’ve ever launched an EC2 instance on AWS, you were already working inside a Virtual Private Cloud (VPC). A VPC is essentially the virtual network that controls all your networking activities. Its setup determines how different parts of your infrastructure communicate with each other and how they access the public internet. In this project, the goal is to build an environment where an auto-scaling group automatically handles the provisioning and termination of EC2 instances, while elastic load balancers evenly distribute incoming traffic across those instances. DEFINITION OF TERMS VPC: Subnets: Internet Gateway: Load Balancer: Route Table: Launch Template: High Availability: USE CASES Being able to scale a web application and evenly distribute incoming traffic across mult…  ( 13 min )

A few months back, the tech world got hit with a wave of panic-inducing headlines. CEOs and tech leaders were on stages everywhere claiming that massive percentages of their code was now AI-generated. If you weren't on board, you were basically toast. This kicked off what I can only describe as a spending frenzy. Companies started signing six and seven-figure contracts for AI coding tools, desperate not to fall behind. The question everyone was asking was simple: "How do we get our entire team using AI?" Now? The conversation's changing. The companies that jumped in early are starting to ask a much harder question: "Is this actually worth it?" We've moved past the hype cycle into the messy reality of execution. Instead of "Are we using AI?" teams are asking "Are we using it well?" And here…  ( 11 min )

Quality is subjective. Architecture is judgemental. So how on earth do we measure it? Every architecture review, every design workshop, every committee meeting eventually hits the same wall. Someone asks: “But is this actually good?” We pretend the answer lives in metrics. Response times. Availability. Coupling scores. Maturity models. Dashboards filled with comforting colours. We convince ourselves that if the numbers are green, the architecture is good. That is the uncomfortable reality: half the time, those numbers are illusions. They tell part of the story. I’ve witnessed perfectly green dashboards collapse the moment real business pressure appeared. Two architects can stare at the same design and read entirely different realities. One sees elegant decoupling. The other sees over-e…  ( 8 min )

Look, my client spent $100 to $150 last month on Clerk for a project with around 15,000 users. That's when I realized there might be a better way. Don't get me wrong. Clerk is amazing. Beautiful UI. Works out of the box. Perfect for quick projects. But here's the problem. You hit 10,000 users? That's $25/month. Add organizations? Extra $100/month. Want MFA? Another $100/month. SSO? $50 per connection. Suddenly, your "simple" auth costs more than your server. So I tested 7 open source alternatives. Here's what I found. Before we dive in, let's be fair to Clerk. They nail the developer experience. Drop in their components, and boom. You have login, signup, and user profiles. No thinking required. Their multi-tenancy is excellent. Organizations work perfectly. The dashboard is polished. Bu…  ( 9 min )

There's a strange paradox in enterprise technology right now. Every organisation is talking about AI. Every board wants it. Every CIO feels the pressure to "deploy something meaningful, fast." But behind the excitement, there's a quieter truth most leaders know but rarely say out loud: AI fails more often than it succeeds. 60-80% Why AI Projects Fail: A Pattern Every CIO Recognises 1.1 AI Projects Start Without a Real Business Problem "We want predictive analytics." Smart CIOs flip the model: They start with the pain point, not the aspiration. 1.2 The Data Isn't Wrong — It's Contextually Blind AI models fail when: CMDB is incomplete 1.3 There Is No Governance Framework for AI Decisions Without governance, teams hesitate around: Who approved an AI-driven action?

‘Two for the Money’ Rewatchable Breakdown Bill Simmons, Chris Ryan and Cousin Sal dive back into the 2005 sports thriller Two for the Money, starring Matthew McConaughey, Al Pacino and Rene Russo. They kick things off with a cold open before digging into the film’s high-stakes betting scenes (1:53), debating the single most rewatchable moment (30:13) and rolling out their signature “Categories” segment at 48:33. Along the way you get that classic Ringer camaraderie—sharp takes, playful jabs and a favorite Monday night parlay vibe—peppered with sponsor shout-outs from Subaru’s Share the Love event and a friendly State Farm reminder. It’s part sports analysis, part movie club, and all about the gamble. Watch on YouTube  ( 6 min )

I've been taught by the best to always use it. It makes code clean even though it's a hell to maintain sometimes. I'm an avid user and perhaps a fan, since it makes JavaScript feel like the other tier-one languages, e.g., Java (I know I said tier 1 language). But if I were to be sincere, I've never had it save my ass on any one day. Maybe until today. I've got myself running a project that works with React Native on the front end and Express/Supabase on the Backend. The mobile app stack, I'll swear by the way.

Most UI tests today still look like this: you code the steps, you hard-code selectors (IDs, XPath, CSS), you pray they don’t break on the next release. This works… until: the accessibility tree is a mess, the app runs inside a WebView, the UI is legacy or hybrid, or there is no reliable locator at all. At that point, traditional automation just gives up. I’ve been working on a different approach: Instead of hard-coding selectors and steps, let an AI agent build the locator and the action at runtime. This is what our project, AI Agent, is about. 🚀 AI Agent is open source & early-stage.

In September 2025, the Intergenerational Open Geospatial Carbon Registry (OGCR) was officially launched under the funding of Horizon Europe, marking a major step forward in the creation of an open, transparent, and scientifically robust framework for carbon accounting across the EU. The initiative brings together more than thirty partners, including universities, research institutes, SMEs and NGOs, and aims to run through 2029, with an investment of €11.5 million. The project’s ambition is broad: to offer Europe’s 9.1 million farmers and forest managers simple, affordable tools to measure, verify, and certify carbon sequestration and ecosystem-service benefits from their land-management practices. At the heart of OGCR’s innovation is the creation of harmonized, updateable baseline data on soil carbon along with biomass and peat carbon. These geospatial carbon baselines, scalable from local to pan-European level, are intended to underpin fair, transparent certification and remuneration under the upcoming framework of Carbon Removals Certification Framework (CRCF).

As Flutter developers, we've all been there. Your app crashes in production, users abandon it, and you don't find out until the 1-star reviews start rolling in. Traditional crash analytics tools are great, but they come with their own problems: complex setup, vendor lock-in, privacy concerns, and that dreaded delay before you actually see what went wrong. What if you could get crash reports instantly, exactly where your team already communicates? Don't get me wrong — tools like Firebase Crashlytics and Sentry are powerful.

Microsoft’s Xbox Series S is the breakout star of Black Friday 2025. The compact console is selling for a compelling $349 at major retailers. This price makes it the most affordable gateway into the current generation of gaming. The deal is available now through the holiday shopping weekend. 🔴👉 https://tinyurl.com/y4szx7ju Xbox Series S Black Friday Gamers are flocking to this offer for its unmatched value. According to Reuters, early sales data shows a significant spike in Xbox Series S transactions. This trend highlights a strong consumer shift toward budget-conscious entertainment. Why The $349 Price Point Is a Game-Changer Its integration with Xbox Game Pass is the killer feature. Subscribers get immediate access to a vast library of games. This combination of affordable hardware and a rich software library presents a complete, low-cost ecosystem. Breaking Down The Console’s Capabilities The main compromise is its digital-only nature. There is no disc drive for physical media. This makes a stable internet connection essential for downloading games and updates. Market Impact and Consumer Choice The long-term effect benefits the entire Xbox ecosystem. More consoles in homes drive Game Pass subscriptions and digital game sales. This creates a recurring revenue model for Microsoft that extends beyond the initial hardware sale. The Xbox Series S at $349 is a near-perfect Black Friday deal for anyone entering the current console generation.  ( 6 min )

One wrong API endpoint in production can cost you users and revenue instantly.

Why Developers Are Turning to LLMs for Automation A common question from Google’s People Also Ask: “Can AI build no-code workflows?” AI is finally good enough to move from suggestions → actual implementation. generating workflow architecture writing n8n expressions creating conditional logic generating regex for webhooks handling pagination & loops producing clean API call formats This means instead of manually assembling 20+ nodes, The Real Experiment: Bu…  ( 8 min )

Most crypto trading still relies on centralized systems; fast, yes, but fragile. A decentralized exchange flips that model entirely. With trustless execution, transparent mechanics, and user-owned assets, developers finally get a foundation that’s predictable, verifiable, and free from middlemen. That’s the direction we’re taking with Haveto: True ownership → no third-party custody Peer-to-peer trading → secure by design Transparent execution → every interaction verifiable on-chain High throughput → smart sharding keeps performance smooth For anyone exploring decentralized infrastructure or designing trading experiences that don’t depend on centralized control, this is a space worth paying close attention to. Would love to hear how you’re approaching decentralized trading, or what features matter most to you as a developer.  ( 6 min )

Spring is paradoxical. It “solves” problems it created — and trained a generation of developers to understand Spring, not software engineering. Dependency Injection everywhere (even when there’s 1 implementation). Interfaces for everything (even when there’s 1 implementation). Annotations as the new programming language. And @Transactional as a magical forcefield masking the fact that no one understands what should actually be atomic. JDBC? SQL? DB design? Transaction boundaries? Most Spring shops never touch them directly — they let the framework decide. The result: the classic Enterprise Java Happy Meal. Dumb, anemic JPA entities Procedural service classes with 10+ injected dependencies DTO ↔ Entity mapping hell Mock-infested tests AOP/DI voodoo that “just works” until it re…  ( 9 min )

Multitenancy in Yii2: Practical Guide and Code Examples Multitenancy is a powerful architectural pattern that allows a single application instance to serve multiple tenants (clients or organizations), keeping their data isolated. Yii2, being a flexible PHP framework, can be adapted for multitenant applications in several ways. In this article, I'll show you how to implement a basic multitenant setup in Yii2, including code snippets and best practices. Single Database, Shared Schema: All tenants share the same tables, with a tenant_id column to separate data. Single Database, Separate Schemas: Each tenant has its own set of tables (schema). Multiple Databases: Each tenant has a dedicated database. For this example, we'll use the Single Database, Shared Schema approach, which is common and…  ( 7 min )

Last week, I spent over two hours helping a client build an AI-powered chatbot for their wellness e-commerce site. I set up a sophisticated RAG system using Cloudflare Vectorize, wrote custom vectorization scripts, and carefully configured Workers AI bindings. The client was pleased with the work. Everything functioned perfectly. Then, fifteen minutes after our session ended, he messaged me: "I just built the same thing using AI Search in 15 minutes." I had over-engineered a solution that could have been 10x simpler. Here's what happened, what I learned, and how to choose the right approach for your project.

AI-assisted coding has been evolving fast, but until now, it often felt like a patchwork solution. You ask for a snippet, get a block of code, and try to fit it into your project. Sometimes it worked. Sometimes it broke everything. Enter Google Antigravity—a shift that changes how AI integrates with development workflows. Breaking Work into Smaller, Manageable Parts One of the biggest hurdles with AI coding has been context. Traditional AI tools are great at generating code snippets but struggle to understand the flow of your project. Antigravity tackles this by connecting directly to your editor and understanding the full codebase. This means it can: Run commands in your terminal automatically Install dependencies on its own Build and place components in the correct folder Test frontend features in a browser and fix issues on the spot This is more than autocomplete. It’s collaboration at a new level. Towards Enterprise-Grade AI Development Antigravity feels like the first step toward full enterprise AI tools. Imagine: Shared workspaces for your team Project-level memory that remembers context across sessions Secure team access and version history Real workflow integration instead of isolated AI snippets AI is no longer just assisting—it’s becoming part of the development workflow, capable of handling real projects end-to-end. What This Means for Developers This approach promises cleaner components, easier debugging, and a smoother workflow. It’s a vision of AI as a true partner in coding, not just a code generator. I’m excited to see how far this can go. Could we soon have AI tools that function like a full teammate, understanding projects, maintaining context, and supporting real development just like enterprise software does today? What do you think? Could this change the way we code professionally?  ( 7 min )

Problem Statement Git Flow and GitHub Flow are two Git branching strategies that help teams collaborate on code without stepping on each other's toes—you pick one when your repo starts feeling chaotic during feature development or releases. You encounter this daily when juggling multiple features, hotfixes, or deploys: one dev merges a breaking change, another can't test locally, and suddenly everyone's yelling in Slack. Choosing the right flow keeps your main branch stable and ships code faster. Both strategies organize Git branches to isolate work, but Git Flow is structured for planned releases, while GitHub Flow prioritizes simplicity and constant integration. master: Always production-ready code. develop: Integration branch for ongoing work. feature/ branches: Off develop for new fe…  ( 7 min )

Infrastructure as Code has completely changed how cloud resources are created and managed. Terraform enables you to deploy AWS services using simple, declarative configuration files. This article explains how Terraform interacts with AWS, how authentication works, and how to create both a VPC and an S3 bucket with an implicit dependency between them. Terraform uses the AWS provider to communicate with AWS services. The provider needs valid credentials, which can be configured in several ways: Using the aws configure command to store credentials inside ~/.aws/credentials Setting environment variables such as AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY Using IAM roles when running Terraform from EC2, ECS, or Lambda Using AWS SSO or shared credentials files The IAM user or role must have pe…  ( 7 min )

One of the most useful patterns in software development — and one that is available in many languages, not just Swift — is dependency injection. When I first learned about it over a decade ago, I started using it everywhere possible. It’s a simple idea with a surprisingly big impact. Here’s why it’s worth mastering. One of the biggest advantages of using dependency injection is that it makes our code immediately more testable. Even in projects full of singletons, we can break apart large chunks of tightly coupled code into smaller, more loosely coupled components. Our implementations rely more on protocols (interfaces) rather than concrete classes, making it easier to swap or replace them. By depending on abstractions rather than concrete implementations, each component can focus solely on…  ( 10 min )

Modern CSS is nothing short of incredible. It gives us the tools to craft rich, interactive, and visually stunning experiences on the web. But with this surge in capability comes a new weakness—not in CSS itself, but in the way we work with it. When I started my career as a web developer, writing CSS often meant inventing hacks to work around what it couldn’t do. Those days are far behind us. Today, CSS offers advanced layout systems, 3D transformations, and highly flexible animation tools. Yet most of the challenges we face in modern CSS aren’t about missing features—they stem from how we author it. This is why the future of CSS might not live in plain text files at all, but in visual creation tools. That idea might sound outrageous at first, but bear with me—I’ll try to make the case.

So on Nov 3rd, after months of feeling completely lost about what I want to do in the future, I finally decided on my path. That path is DEBMO. It originally started as something much smaller, called Project-DB, a drag-and-drop (DnD) query tool that would let tech and non-tech people work with databases without hassle. The idea was to connect multiple databases (MariaDB, PostgreSQL, even Snowflake warehouses), run queries, and process data in one place. After I met the two people who later joined me on this journey, we realized it needed to be more than “just” a query tool. That’s when we came up with things like Excelerator, Data Studio, and a more advanced permissions system to support the way teams actually work with data together. Right now, I’m the only one working on the development side. There have already been a lot of sleepless nights going into this, and I don’t regret even 0.1% of it. So far, we’ve built: The main project structure Connections to Buckets / DB / Redis Login with 2FA Role-based permissions The Admin Portal It’s tiring and hard, but it’s also exciting to see it slowly become real. Our current goal is to have a free testing phase starting around Jan/Feb, where anyone can try the MVP for a few months. During that time we’ll collect feedback, fix bugs, and ship the features we still have planned. The MVP will stay free during this testing period before we eventually move to paid plans later on. If you’re interested in the project, want to follow the development, or give feedback before and during the testing launch, you can join the DEBMO Discord server (link below). Until then, I’ll be posting weekly devlogs here on dev.to to share progress, decisions, and struggles along the way. Wish me luck on this journey. 🚀 Link: https://discord.gg/zJC8tU2y  ( 7 min )

Artificial Intelligence has revolutionised lives in the past few years. We’ve moved from simple chatbots and prediction tools to a new kind of smart system—AI agents. These agents don’t just respond to questions. They can think, plan, and take action on their own. They can talk to people, use software tools, and even work with other agents to reach goals. But what makes all this possible is something most people don’t see: AI agent frameworks. These frameworks are the hidden structure that helps build, run, and manage AI agents. They are what turn language models into full digital workers. Let’s discuss them in detail.

TypeScript's type system is a powerful tool for building robust applications. Features like utility types and interface inheritance feel like natural ways to reduce repetition and structure code. However, when overused, they can silently introduce complexity and fragility that undermine the very maintainability we seek. Utility types like Pick, Omit, and Partial are incredibly convenient. They allow us to create new types on the fly, often saving us from writing verbose type definitions. The Problem: Overusing them, especially nested within other utilities, creates "type opaqueness." The origin and contract of a type become obscured, making the code harder to understand and reason about. Consider this example: type User = { id: string; name: string; email: string; createdAt: Date; …  ( 8 min )

Overview HashMap is a widely-used data structure in Java that implements the Map interface for storing key-value pairs. It delivers O(1) time complexity for fundamental operations like insertion and retrieval under typical conditions. HashMap utilizes an array of nodes as its foundation, commonly referred to as the bucket array. Each bucket can accommodate multiple entries through either a linked list or tree structure when collisions occur. Every entry in the HashMap is represented by a Node object that implements the Map.Entry interface: static class Node implements Map.Entry { final int hash; // Hash code of the key final K key; // The key V value; // Associated value Node next; // Reference to next node } Hash Computatio…  ( 8 min )

Similarly, by carefully orthogonalizing gradient updates, we can drastically improve convergence speed during training. This novel optimizer em…  ( 7 min )

Hey Dev.To community! 👋 I've just launched a new open-source project that might be of interest to those building CI/CD pipelines or managing internal security tooling: Ephemeral Vulnerability Scanner. This is a 100% client-side application built with vanilla JS/HTML/CSS. You clone it, open index.html, upload your system inventory (inventory.json), and get an instant, privacy-safe vulnerability report. 💡 Why this architecture? It addresses the privacy concern: No sensitive system data leaves your device. It's fast and eliminates backend maintenance overhead. It's transparent: you can literally inspect the app.js source to see the entire logic. Under the Hood: We use platform-specific commands (PowerShell, dpkg, rpm, brew) to generate the initial JSON inventory. The analysis logic hits MSRC CSAF API (Windows), OSV.dev API (Open Source), and CISA KEV for a strict, verified lookup. Results are grouped into clean, actionable "Package Cards" with the minimum safe version calculated automatically. Check out the repo, try the demo, and let me know what you think of the client-side approach for security analysis! 🔗 Live Demo: VulnScan  ( 6 min )

Body: I’ve been building a lot of AI agents lately. The logic is usually fun to write, but I kept hitting the same wall: State Management. LLMs are stateless. As soon as the session ends, the context is gone. Sure, you can pass the chat history, but once that hits the token limit, your agent gets amnesia. The standard solution is "Just use a Vector Database." But setting up a dedicated Pinecone or Weaviate instance, configuring the embedding pipeline (OpenAI/HuggingFace), and writing the chunking logic just to store a few user preferences felt like massive overkill for my side projects. I didn't want to manage infrastructure; I just wanted my agent to remember that my favorite color is blue. So, I spent the last few weeks building a dedicated API to abstract all that boring stuff away. It’…  ( 8 min )

From the early days of mainframes to the modern cloud-based ecosystems, IT continues to evolve at a breakneck pace. One of the most revolutionary forces shaping IT today is Artificial Intelligence (AI). AI in Everyday Technology Artificial Intelligence is no longer a futuristic concept—it’s already part of our daily lives. From smart assistants like Alexa and Siri to recommendation engines on Netflix and Amazon, AI is making technology smarter, faster, and more intuitive. In IT, AI is being leveraged for: Cybersecurity: AI algorithms can detect anomalies in network traffic, identify potential threats, and respond to breaches faster than human t…  ( 7 min )

JavaScript, by its nature, is a single-threaded language. This means it traditionally executes one operation at a time on the browser's "main thread." This main thread is responsible for everything a user sees and interacts with: rendering the UI, handling user input, running animations, and executing all your application's JavaScript. While this single-threaded model simplifies development in many ways, it presents a significant challenge: what happens when your JavaScript needs to perform a heavy, CPU-intensive task? The answer, historically, was a frozen UI, unresponsive buttons, and a frustrating user experience. Enter Web Workers. Web Workers provide a way to run JavaScript scripts in background threads, separate from the main execution thread of a web page. By offloading CPU-intensiv…  ( 12 min )

Welcome to Day 46 of the #80DaysOfChallenges journey! This intermediate challenge implements a Simple Moving Average (SMA) calculator using an efficient sliding window approach that maintains a running sum, achieving O(n) time complexity while avoiding redundant calculations.

Most companies still treat privacy as a policy problem. That difference — between writing rules and enforcing them — is what separates organizations that talk about responsible data use from those that actually achieve it. The Weekly Translation Failure Every week, legal, product, and engineering teams sit down to align on privacy and responsible data use. And every week, they run into the same challenge: It’s not a communication problem. A privacy policy that reads cleanly in a spec document becomes a maze of implementation questions the moment it meets code: Policy teams speak in rights, obligations, and business rules. The result? The Missing Layer: A Shared Operational Foundation What’s missing isn’t collaboration — it’s a common operational foundation. This is why privacy must be treated as a systems problem. That’s the core principle behind emerging privacy infrastructure — where legal definitions, business policies, and data models converge into a single executable framework. When obligations are expressed as code, they become: When Policy Lives in Infrastructure When privacy is embedded directly in infrastructure, the dynamic between teams changes entirely: That’s not just better governance — it’s a better growth model. Instead of being boxed in by complexity, teams gain the freedom to innovate safely with sensitive data — whether it’s for AI, analytics, personalization, or compliance. Privacy as a Competitive Advantage Enterprises that get this right stop playing defense with privacy. Because when privacy becomes part of your stack, not just your policy binder, you don’t just comply. You scale responsibly. You innovate with confidence. And you turn privacy from a blocker into a feature of your growth model.  ( 7 min )

Pay-Per-Click (PPC) advertising has become one of the most effective and widely used online marketing models for businesses of all sizes. Whether you are a small brand looking to attract local customers or a large company aiming to scale globally, PPC gives you immediate visibility, measurable results, and complete control over your advertising spend. To use PPC effectively, you must understand how it works, what factors influence performance, and how to optimize your campaigns for better results.

In the React ecosystem, we’ve spent years debating which state management library to use — Redux, MobX, Recoil, Zustand, Jotai, XState, and the ever-humble React Context. But the real architectural question we often forget is far more fundamental: Where should state live? How far should it travel? And how do we prevent state from becoming a silent source of UI slowdown? Let's discuss in depth on an unglamorous yet powerful topic that every UI architect should obsess about: State Boundaries — The Most Important Concept in Scalable React Apps State boundaries define how far a piece of state is allowed to influence the UI. If your components re-render “too much,” lag under load, or behave unpredictably, the root cause 90% of the time is: Your state boundaries are broken. Let’s understand th…  ( 9 min )

If you are diving into Solana development, you have probably heard terms like "Ed25519" and "Proof of History" almost always. But what do they actually mean? How do they work? Let us break down the cryptography that makes Solana one of the fastest blockchain networks available. Think of cryptography as the art of securing communication in hostile environments. In the blockchain world, it is what allows you to prove you own an account, sign transactions, and trust that data hasn't been tampered with, all without needing a central authority to verify everything. At its core, cryptography uses mathematical functions that are easy to compute in one direction but nearly impossible to reverse. It is like mixing paint colors: easy to mix blue and yellow to get green, but try separating that green…  ( 8 min )

What is a CDN? A Content Delivery Network (CDN) is a strategically distributed system of servers designed to deliver internet content with maximum speed and efficiency to users worldwide. According to recent industry data, over 80% of global web traffic now flows through CDN infrastructure, making it an essential component of modern digital infrastructure. When a user accesses a website, the CDN intelligently delivers content from the server geographically closest to that user—known as an "edge server" or "Point of Presence" (PoP)—rather than routing all requests to a single origin server. This distributed architecture fundamentally transforms how content reaches end users, reducing latency by up to 50 milliseconds for 95% of internet users globally. 1.

You need a 6-digit code to sign in, but don’t have an authenticator app on this device—whether it’s a new laptop, a work computer, or a quick test. That’s where 2FA2FA comes in. 2FA2FA Live Auth is a free, browser-based Time-based One-Time Password (TOTP) generator. Paste a Base32 (binary-to-text encoding scheme) secret or import it from a QR code image, and your time-based codes appear instantly—no account, no install, and nothing stored. The math runs locally in your browser and disappears when you close the page. If you later want encrypted storage and bulk code management, there’s a separate Manager, but Live Auth keeps first use as simple as it gets. Try it here.

Recently, I released the code-review gamification project “Code Review Game.” This time, I created another game called “Bug Sniper,” where the goal is to find bugs hidden in code. https://bug-sniper.goofmint.workers.dev/ Code Review Game was originally designed for conference booths so that attendees could give it a try. However, it ended up becoming something that required fairly serious review skills. While this was useful from a learning perspective, it required a PC and wasn’t something you could casually enjoy. With that in mind, I created Bug Sniper as a more lightweight, pick-up-and-play experience. Bug Sniper is a game where you keep finding bugs in code for 60 seconds straight. Each problem contains around one or two bugs. For example, consider the following code: function get…  ( 7 min )

Observables This article aims to explain how observables help or fit in into the use case of sharing data among views. Before that, we need some context. When we want to share data among views, we usually use classes instead of structs. The main reason is that whenever we use structs, each view will have its own copy of said struct, so it does not really fit the use case if you would like to share data among views. To be able to share data among views, you need to use classes. import Combine class Counter: ObservableObject { @Published var count = 0 } The above code contains a class called Counter and it inherits ObservableObject. SwiftUI makes use of the subscriber-publisher model. In this case, the Counter class publishes the count variable. struct ContentView: View { @State…  ( 7 min )

Arrays in JavaScript are like tiny storage shelves where each item has a number tag (index). They let us store multiple values together and work with them easily. What Are Arrays? An array is a collection of elements. Arrays are represented using square brackets [], like this: let arr = [4, 8, 7, -1, 0, 4, 9]; Indexing in Arrays So for an array of n elements, the valid index range is: Examples: console.log(arr[2]); // 7 console.log(arr[25]); // undefined Array Length console.log(arr.length); // 7 Arrays Are Mutable 1️⃣ push() let arr = [1, 2, 3]; arr.push(4, 5); console.log(arr); // [1, 2, 3, 4, 5] 2️⃣ pop() let arr = [1, 2, 3, 4, 5]; arr.pop(); console.log(arr); // [1, 2, 3, 4] 3️⃣ unshift() let arr = [1, 2, 3]; arr.unshift(4, 5); console.log(arr); // [4, 5, 1, 2, 3] 4️⃣ shift() let arr = [1, 2, 3]; arr.shift(); console.log(arr); // [2, 3] 5️⃣ splice() A powerful method used to add, remove, or replace elements. Examples: let arr = [5, 6, 7, 8, 9, 10, 11, 12]; arr.splice(3); // delete all from index 3 arr.splice(3, 1); // delete only element at index 3 arr.splice(3, 2, "raj", "shekhar", "john"); // replace 2 items Given: let friends = ["sheldon", "rachel", "ross", "chandler", "monica", "penny"]; 1️⃣ Remove "sheldon" and add "pheobe" friends.shift(); friends.unshift("pheobe"); 2️⃣ Remove "penny" and add "joey" friends.pop(); friends.push("joey"); 3️⃣ Add "emma" between "rachel" and "ross" friends.splice(2, 0, "emma");  ( 7 min )

Cross-Compiling Go Applications: A Comprehensive Guide Introduction Go, or Golang, is renowned for its efficiency, simplicity, and built-in support for concurrency. However, one of its most powerful features, often overlooked, is its seamless support for cross-compilation. Cross-compilation is the process of compiling code on one platform (the build platform) to create executables that run on a different platform (the target platform). This feature is invaluable for developers targeting a wide range of architectures and operating systems, especially in environments like embedded systems, mobile development, and cloud infrastructure. This article delves deep into the world of cross-compiling Go applications, covering prerequisites, advantages, disadvantages, features, and providing practi…  ( 9 min )

"Security bolted on after development is a band-aid. Security designed in from day one is the foundation." What if I told you that 92% of data breaches could be prevented by embedding security into the earliest design phases, not patching it after deployment?

Getting Inside a Running Container When your container is already running, you can access its shell using: docker exec -it bash If the container doesn't have Bash installed, try: docker exec -it sh This lets you debug, inspect logs, check files, or test configurations from inside the container. When Your Container Isn’t Running (or Exits Immediately) When a container won’t start, docker exec won’t work. docker run -it --entrypoint=/bin/bash This forces the container to start with a shell, even if its actual entrypoint fails. Tip: Useful Docker Compose Commands Stop services and remove containers + volumes docker compose -f down -v The -v flag removes volumes as well. Start services in detached (background) mode docker compose -f up -d The -d option keeps everything running in the background so you can continue working.  ( 6 min )

Gartner estimates that over 80% of data teams spend more time finding data than analyzing it, largely due to missing lineage, unclear ownership, and manual documentation. As organizations scale their data ecosystems, a robust automated data lineage solution becomes essential—not just for governance, but for analytics accuracy, regulatory compliance, and operational efficiency. Data lineage is no longer a “nice to have.” In modern enterprises with cloud warehouses, diverse data tools, and complex pipelines, manual lineage quickly becomes outdated and unreliable. Automation bridges this gap by continuously tracing data flows across systems, helping teams understand where data comes from, how it transforms, and where it goes. This guide explains what an automated data lineage solution does,…  ( 9 min )

Next.js 16 introduces a new file-convention: proxy.js / proxy.ts (often “Proxy”) which supersedes the older middleware.js. This feature allows you to intercept HTTP requests early (before routing/rendering) and run custom logic—redirects, rewrites, header manipulation, or forwarding (proxying) to another service. In e-commerce (or any frontend/back-end scenario) this gives you a powerful tool: you can make your Next.js app act as a Backend-for-Frontend (BFF) layer, hiding upstream APIs, consolidating micro-services, enforcing auth, caching, rewriting URLs, etc. This aligns well with many of the architectures discussed in your referenced articles about Next.js for commerce (SSG/ISR/SSR strategies etc).

Industrial fabrication depends heavily on accurate, well-defined BIM models. Whether you’re planning equipment installation, prefabrication, or site coordination, selecting the right Level of Detail (LOD) in BIM determines the accuracy, cost, and constructability of your project. Two of the most commonly compared LODs are LOD 400 and LOD 500. While they may seem similar, they serve completely different purposes—one for fabrication and installation, the other for facility management and lifecycle operations. This guide breaks down the differences, use cases, and best practices to help fabrication teams, contractors, and facility managers choose the right LOD for their needs. The Level of Detail (LOD) defines how much graphical and non-graphical information a BIM element contains. The common…  ( 8 min )

I. The Ambient Revolution I keep seeing the same moment at work. You’re on a call, someone’s sharing their screen, you toss out a weird angle on the problem. Not wrong, just slightly sideways.

Have you ever wanted to build a marketplace where users can buy and sell products using stablecoins without worrying about gas fees? In this article, I'll walk you through how I built Polygon x402 Marketplace, a gasless peer-to-peer marketplace using the x402 protocol on Polygon Amoy. Traditional blockchain marketplaces have a major UX problem: users need to hold native tokens (like MATIC) just to pay for gas fees. This creates friction because: New users need to acquire native tokens from exchanges first Users must manage multiple token balances Gas prices fluctuate, making transaction costs unpredictable The x402 protocol enables gasless USDC transfers by using EIP-712 signatures and a facilitator network. Users only need USDC in their wallet to participate in the marketplace - no native…  ( 8 min )

Something weird happened while we were all busy optimizing for Google. Gen Z stopped using it. Not entirely, obviously. But here's the thing: 40% of young people now use TikTok or Instagram as their primary search engine. Not for everything, but for restaurants, product recommendations, how-to tutorials, and basically anything where they want real human opinions instead of SEO-optimized listicles from 2019. Google's own data confirmed this in 2024. Which must have been a fun meeting. So now TikTok isn't just a platform where people do dances and share life hacks. It's a legitimate search destination with its own ranking factors, optimization strategies, and yes—an algorithm you need to understand if you want anyone to actually find your content. Let's talk about how to rank on a platform t…  ( 13 min )

The future of AI agents relies on their ability to seamlessly and efficiently integrate with vast libraries of tools—from internal databases and company-specific APIs to public services like GitHub and Slack. As professional developers, we know that scaling an agent from five tools to fifty or five hundred introduces critical bottlenecks: context bloat, slow execution, and unpredictable tool invocation. To solve these challenges, we are excited to introduce three advanced features on the Claude Developer Platform that fundamentally change how agents discover, orchestrate, and utilize external capabilities. These features move Claude from simple sequential function calling to intelligent, programmatic orchestration. When building agents that connect to many services (e.g., a five-server MCP…  ( 9 min )

Decoding Movement: Emulating Biological Motion for Smarter Robots Ever watched a cat effortlessly navigate a complex environment and wondered how to program a robot to do the same? We're constantly striving to create robots with the agility and adaptability of animals, but the traditional approach of programming every joint movement is incredibly complex and often fails in unpredictable situations. What if robots could learn to move, not just follow pre-defined paths? This is where neuromechanical emulation comes in. The core idea is to build a virtual model of an animal's body, connect it to a simulated nervous system controlled by a neural network, and then train that system to reproduce real-world movements captured from motion capture data. It allows AI agents to learn motor control …  ( 7 min )

I originally posted this post on my blog a long time ago in a galaxy far, far away. If you want to start a coding blog, don't start with a deep dive of the Linux Kernel or other cryptic topics—unless you're an expert on those topics. TIL posts are shorter posts where you share something you've found or figured out. With TIL posts, you don't have to worry about long introductions or conclusions. Just write a good headline, a code block, a quick explanation, and your sources. And write using your own words, like in a conversation with a coworker. That's enough to make a post worth reading. Don't try to lecture the coding world about what they should do. Start documenting your learning instead. Instead of writing "5 VS Code extensions every coder should install," try "TIL: 5 VS Code extensions I couldn't avoid installing." Or instead of "5 Git commands every coder should know," covering the same basic Git commands every beginner writes about, write "TIL: 5 Git basic commands to use everyday" or "TIL: How Git Status works." Spent 20 minutes or more figuring out something? write a TIL post. That's the easiest way to start a coding blog. Apart from coding, writing has been one of the best skills I've developed as a coder. It's taught me to research, organize, and present ideas clearly. That's why I made it one of the strategies in my book, Street-Smart Coding: 30 Ways to Get Better at Coding. It's the guide I wish I had when I was starting out, trying to go from junior to senior. Get your copy of Street-Smart Coding here  ( 7 min )

Introduction In an era of complex build systems and framework-specific tooling, there's a compelling case for revisiting Make—a build automation tool that has quietly powered software development since 1976. Despite its age, Make remains remarkably relevant for modern development workflows, from React applications to containerized microservices. This blog helps you to understand why Make deserves a place in your development toolkit and how to leverage it effectively in contemporary projects. Every development team faces the same fundamental challenge: managing increasingly complex build and deployment processes. Consider a typical React application workflow: Installing dependencies across multiple directories Running development servers with specific configurations Executing test suites …  ( 9 min )

When writing code in Go we often run into errors that are critical. These are errors that mean our application cannot continue running. To handle these we usually look at two options. We can use panic or we can use log.Fatal. They both stop the application but they do it in very different ways. The main difference is how they treat the defer function. When you use log.Fatal the application stops immediately. It calls a system function called os.Exit(1). This is a hard stop. The program does not look back and it does not run any cleanup code. Let us look at a standard example. Imagine we are connecting to a database in our main function. We want to make sure the database connection closes when the app stops. package main import ( "fmt" "log" ) func main() { fmt.Println("1. Ope…  ( 7 min )

🚀 What is an MCP Server? Think of an MCP Server as a "Universal Translator" between your data and AI models. With MCP: You build an MCP Server once. It exposes your data (Resources), actions (Tools), and templates (Prompts). Any MCP-compliant client can connect to it instantly The beauty of this protocol is its interoperability. An MCP Server doesn't care who is asking for the data, as long as they speak "MCP". Supported Clients include: Claude Desktop App: Connects locally to read your files or query databases while you chat. VS Code (with Extensions): Allows your IDE to "see" external documentation or server logs to help you code better. Zed Editor: Fast, AI-powered coding that leverages your custom MCP tools. The connection is surprisingly simple. It usually happens over stdio (stand…  ( 7 min )

Running AI models locally on consumer devices is increasingly popular but often underestimated in terms of hardware demands. The reality involves far more than just having a powerful GPU it requires a finely tuned system to handle the intense computations, data flow, and thermal challenges. GPU: The Computational Powerhouse GPUs are the cornerstone of AI workloads, performing billions of parallel calculations per second. High end GPUs like NVIDIA’s RTX 4080, 4090, or 5090 are favored for local AI due to their vast VRAM (16GB or more) and Tensor Cores optimized for AI tasks. However, even these powerful cards face limits when running large models or generating long outputs, pushing utilization near 100% and maximizing power consumption.

Earlier this year, during a test run for Replit, an autonomous AI agent accidentally deleted a live production database containing sensitive data from more than 1,200 companies and executives. Multiple outlets reported the same story: The agent “ran unauthorized database commands” This incident made something very clear: We are giving AI agents root access to our most sensitive systems, and we have zero guardrails in place. And yet… companies are deploying these agents into production Right now, when you deploy an AI agent, it typically uses a single API key with God-mode access: # How most AI agents work today STRIPE_API_KEY = "sk_live_..." # Root access to EVERYTHING agent.charge_customer(1000000) # Any agent can do ANYTHING agent.delete_database() # No permission checks agent…  ( 9 min )

Read the original article：How can developers create and manage custom popup views in HarmonyOS? Context Popups are small UI elements that show extra information or tips. They are often used for screen recording, tooltips, or simple notifications. In HarmonyOS, developers can create basic popups with PopupOptions, or fully customized ones using CustomPopupOptions and the @Builder function. Description Standard popups are limited in layout and design. If you need a more flexible popup (for example, with images, custom text layout, or styles), you can create a custom popup using the builder function. There are some important rules when using popups: You can only show a popup after the page is fully built. Showing it too early may cause position or shape issues. You can control the popup’s bac…  ( 7 min )

So… this was actually my first time dealing with a situation like this. That’s when I realized: Before building that dev environment, I paused for a moment to review my production setup. Basically, my production environment runs on Google Cloud Platform (RESTful API, database, storage) and Netlify (frontend deployment). Here’s the simplified architecture: Frontend (Vue.js) → Deployed on Netlify as a static web app 🌐 RESTful API (Flask) → Built with a Dockerfile 🐳 and deployed to Google Cloud Run File Storage 📄 → I use Google Cloud Storage to store user-uploaded documents (like invoices, etc.), organized into several folders based on category 🔐 Database (MySQL) 🗄️ → Hosted on a Compute Engine VM 🖥️ So yeah... production worked. It served real users. But that also meant I had to be careful. At first, I had no idea where to start, so I explored, asked around, and slowly pieced everything together. Here’s how the journey played out 👇 The first thing I had to do was duplicate my production SQL database. # 1. Export production database mysqldump -u root -p app_prod > app_prod_backup.sql # 2. Create a new dev database mysql -u root -p -e "CREATE DATABASE app_dev;" # 3. Import production data into the new dev database mysql -u root -p app_dev < app_prod_backup.sql main 🌿 I knew enough to not touch production code directly. It became my sandbox, my first real “safe space” to test anything I wanted. This part felt like a milestone. Now dev had its own backend service, completely isolated. Next, I updated the environment variables so the dev backend pointed to the dev DB. Then came the storage problem: Yup. After that, I switched the backend to use the dev bucket. Of course, the frontend also needed to point to the new dev API URL. Once everything was separated—DB, bucket, Cloud Run, branch—it felt so good. And honestly? Do you think this setup is on the right track? I’m open to any insights or best practices that could make it even better 🚀✨  ( 8 min )

The history of music production is essentially a history of abstraction. We transitioned from capturing physical acoustic vibrations to manipulating voltage on analog tape, and then to manipulating bits in Digital Audio Workstations (DAWs). Each step abstracted the underlying physics, allowing creators to focus more on composition and less on the medium itself. To understand the workflow shift, it is necessary to understand the underlying architecture. Unlike traditional MIDI sequencers that trigger pre-recorded samples, modern generative audio tools often rely on Diffusion Models and Transformers.

You know, I wrote about Nano Banana just a month ago, and at the time it already felt like a small creative superpower.

Not to see whether it can make pretty images, since we've had enough of that, but to see whether it can actually do something meaningful. I was finding use cases ranging from diagrams that make sense, to infographics that understand the topic, layouts that look like they came from a design team, and even merged scenes that stay coherent instead of collapsing into chaos. And finally, in this post, I'm breaking down the exact use cases and real-world examples that turn Nano Banana Pro from a …  ( 14 min )

Prioritizing a backlog can be one of the hardest challenges for any team. Every task, feature, or improvement can feel urgent and important, and without a clear method, teams risk spending time on work that delivers little value. Conflicting opinions, shifting priorities, and long lists of tasks can make it difficult to know what to tackle first. Weighted Shortest Job First, or WSJF, provides a structured, data-driven approach to this problem. It allows teams to measure the value of work relative to the time or effort required to complete it. By doing so, WSJF highlights the items that will deliver the most impact in the shortest time, helping teams focus on what truly matters. This article explains what WSJF is, how it works, and how teams can apply it effectively. It will guide you throu…  ( 11 min )

Any dynamic update (extension) technique essentially defines a Delta space and the feasible structural composition operations within that space. On reflection, what most people call dynamic updates is nothing more than defining extension points on an already constructed structure and then inserting structures that conform to interface specifications into those points. The complexity of implementing dynamic Delta updates lies in the following three aspects: How should extension points be designed to satisfy unknown Delta update requirements? How can externally introduced Delta structures be seamlessly integrated with the original structure? How can we ensure runtime state consistency before and after Delta updates? Beyond the above three points, we can also ask ourselves: since all b…  ( 8 min )

poi-tl is a Word template engine based on the Apache POI project. Compared to manually programming POI objects to construct Word documents, poi-tl can use ordinary Word files as base templates and replace custom tags within them to generate output files, thus achieving a certain degree of visual design. For example, tags are marked in the template using the {{xxx}} form. Then, during execution, by passing in some control rules and data objects, the output file can be obtained: LoopRowTableRenderPolicy policy = new LoopRowTableRenderPolicy(); Configure config = Configure.builder() .bind("goods", policy).bind("labors", policy).build(); XWPFTemplate template = XWPFTemplate.compile(resource, config).render( new HashMap() {{ put("goods", goods); put("la…  ( 15 min )

Background Engineers vs Managers We engineers want to focus on engineering. It would be great if we only had to deal with engineering, but that's not the reality. For more than 50 years, another role, "manager," has been considered indispensable. Unless you have a team of exceptionally talented individuals or work in an advanced organization like a Teal organization, you will need both engineers and managers. However, because their roles are inherently different, they often clash. Here's a discussion I find intriguing: Maker's Schedule, Manager's Schedule Recently, I've realized there is a third domain that neither engineers nor managers can fully cover.

In daily development, we often need to import and export Excel data, generate Excel and Word reports, etc. Common packages like easyexcel and poi-tl rely on the underlying POI engine, which is bulky and struggles with complex, irregular tables. When creating complex Chinese-style reports, one usually needs to use report engines provided by professional report software companies such as Runqian and FanRuan. Many years ago, Runqian pioneered a nonlinear report generation algorithm that supports symmetric expansion across rows and columns, which later became a leader in commercial reporting software.

DevConnect is Ethereum’s annual week of deep-dive community events. in 2025, it took place in Buenos Aires - the region where crypto actually runs day-to-day finance. I’ve broken it down to the structural takeaways, so you can see where ETHereum is heading now: privacy returns to the core newly presented Kohaku (modular tooling for privacy-preserving wallets), and Tor/onion services show that Ethereum is reinforcing privacy at the protocol edge, treating user protection as priority infrastructure. zero-knowledge for everyone ZK tooling is no longer limited to cryptographers. developers are already integrating proofs into wallets and cross-ecosystem transfers - meaning ZK is becoming part of the standard development stack. security evolves into a full-stack discipline audits are still necessary, but no longer central. teams now focus on threat modeling, chain-split scenarios, monitoring, and architecture weaknesses - the real attack surface. L1 strengthens its role, L2 carries the throughput bigger gas limits are being considered, L2s handle the speed, and Ethereum continues its slow march toward ossification. the ecosystem is aligning around durability first, convenience second... cross-chain UX to be finally fixed the new Ethereum Interop Layer aims to let users act across rollups without switching networks. One signature, multiple chains. I hope Ethereum's direction has now become clearer for you: the project is finally maturing and aligning its roadmap with how people actually use crypto today, not how it was imagined years ago 💭  ( 6 min )

La inteligencia artificial moderna ha avanzado enormemente en el procesamiento de lenguaje natural (NLP), pero sigue enfrentándose a una pregunta esencial: ¿entienden las máquinas el lenguaje o simplemente lo imitan? Aquí entra en juego el conocimiento lingüístico, el conjunto de reglas, estructuras y significados que los humanos utilizamos para comunicarnos de manera coherente. Durante décadas, el NLP se apoyó en la lingüística tradicional. Los sistemas estaban construidos sobre gramáticas, parsers y reglas sintácticas, reflejando una comprensión estructural del idioma.

Modern artificial intelligence has made tremendous progress in natural language processing (NLP), yet it still faces a profound question: do machines truly understand language, or are they simply mimicking it? This is where linguistic knowledge comes into play — the set of rules, structures, and meanings humans use to communicate coherently. For decades, NLP was grounded in traditional linguistics. Early systems relied on grammars, parsers, and syntactic rules, reflecting a structured understanding of language. However, with the rise of deep learning, this approach gave way to data-driven models. Neural networks began to infer statistical patterns, bypassing explicit linguistic theory. Today, models like BERT, GPT, and Gemini seem to grasp meaning. Yet they do so implicitly — by learning a…  ( 7 min )

Surgical Precision with AI: A New Era in Lung Cancer Staging Imagine the anxiety of waiting for a lung cancer diagnosis, compounded by the uncertainty of accurate staging. Misdiagnosis can lead to inappropriate treatment, impacting patient outcomes and quality of life. But what if AI could provide a more precise, transparent, and reliable staging process? We're entering a new era where AI doesn't just classify images; it understands anatomy. The core concept is a hybrid approach: using deep learning for precise image segmentation, then applying rule-based clinical knowledge for staging.

So… I just went through two “interviews” that turned out to be scams. Both followed the same playbook: they gave me a repo link, told me to share my screen, and asked me to install + run the project during the call. On a first interview. That alone feels off, right? But these scammers have gotten smarter. They’ll do the whole friendly intro, talk about the company, show you a project, ask about your past work — the whole thing feels legit until suddenly you’re the one walking them through a repo on your machine. Luckily, I had a gut feeling something wasn’t right.

Originally published in the LaunchDarkly Docs Part 1 of 3: Rage Click Detection with LaunchDarkly The holidays are around the corner and with it comes the expected uptick in traffic, and as traffic increases the need to preserve user experience becomes that much more imperative. You can ship out a new feature, everything seems to be going as planned, and then all of a sudden you start to see a spike in support tickets. The error logs aren’t helpful or show nothing and the metrics look fine. So, what happened? In this three-part series, we'll explore how LaunchDarkly's session replay and observability features help you detect, diagnose, and fix user experience issues in real-time. Part 1 covers the fundamentals: what rage clicks are, how to detect them, and how to get started with session …  ( 13 min )

This weekend, Andrej Karpathy, the former director of AI at Tesla and a founding member of OpenAI, decided he wanted to read a book. But he did not want to read it alone. He wanted to read it accompanied by a committee of artificial intelligences, each offering its own perspective, critiquing the others, and eventually synthesizing a final answer under the guidance of a "Chairman." To make this happen, Karpathy wrote what he called a "vibe code project" — a piece of software written quickly, largely by AI assistants, intended for fun rather than function. He posted the result, a repository called "LLM Council," to GitHub with a stark disclaimer: "I’m not going to support it in any way... Code is ephemeral now and libraries are over." Yet, for technical decision-makers across the enterpris…

Researchers at Alibaba’s Tongyi Lab have developed a new framework for self-evolving agents that create their own training data by exploring their application environments. The framework, AgentEvolver, uses the knowledge and reasoning capabilities of large language models for autonomous learning, addressing the high costs and manual effort typically required to gather task-specific datasets. Experiments show that compared to traditional reinforcement learning–based frameworks, AgentEvolver is more efficient at exploring its environment, makes better use of data, and adapts faster to application environments. For the enterprise, this is significant because it lowers the barrier to training agents for bespoke applications, making powerful, custom AI assistants more accessible to a wider rang…

Monte Carlo Neural Operators: Democratizing Physics Simulations Tired of wrestling with complex Partial Differential Equations (PDEs) to simulate real-world phenomena? Imagine effortlessly predicting fluid flow, heat transfer, or structural behavior without spending hours tweaking traditional numerical solvers. This is where a novel approach based on machine learning, specifically a Monte Carlo-inspired neural operator, changes the game. The core idea revolves around learning a direct mapping from a PDE's input parameters to its solution, sidestepping the need for iterative calculations. This "operator" is implemented as a neural network which doesn't make any assumptions about the underlying structure of the problem, using random samples to estimate the integral representation of the P…  ( 7 min )

But it is my learning journey, and I hope it will be helpful for others who are just starting out with Go and web development. Tis series will be focused on building a simple web application using Go, HTMX, sqlc with PostgreSQL, goose and Tailwind CSS for styling (I don't know why, but it seems that the fabric of the universe itself demands any web application to have Tailwind nowadays, so here it is). sqlc – Generate type-saf…  ( 14 min )

For over 50 years, the Unix philosophy has shaped how we build software. Its principles feel right in a way that transcends trends and languages. But why? In "The Art of Unix Programming," Eric Raymond distilled Unix wisdom into 17 rules. These aren't arbitrary guidelines—they're a coherent system based on one fundamental insight. That insight is the Principle of Independent Variation (PIV). Let me show you why Unix got it right, and why these rules still matter in 2025. The Unix philosophy emerged from the design of Unix at Bell Labs in the 1970s. Its core tenets: Write programs that do one thing well Write programs that work together Write programs that handle text streams, because that is a universal interface These ideas evolved into 17 specific rules documented in Raymond's "The Art o…  ( 22 min )

🔹 What is Authentication? It’s the process of verifying who a user is. 🔹 What is Authorization? It’s the process of verifying what a user is allowed to do after logging in. ✅ Step 1: Authentication – Common Methods • Username & Password – Basic login • OAuth – Login via Google, GitHub, etc. • JWT (JSON Web Token) – Popular for token-based auth • Session-Based – Stores session on server with session ID ✅ Step 2: How Login Works (JWT Example) User sends email & password to server Server verifies and sends back a JWT JWT is stored in browser (usually localStorage) On each request, client sends JWT in headers Server checks token before giving access ✅ Step 3: Authorization Types • Role-Based Access – Admin, Editor, User • Resource-Based – Only owners can edit their content • Route Protection – Block some pages unless logged in ✅ Step 4: Protecting Routes (Frontend Example) if (!localStorage.getItem('token')) { window.location.href = '/login'; } ✅ Step 5: Backend Route Protection (Express.js) function authMiddleware(req, res, next) { const token = req.headers.authorization; if (!token) return res.status(401).send('Access Denied'); // Verify token and decode user info next(); } ✅ Step 6: Common Tools & Libraries • bcrypt – Hash passwords • jsonwebtoken (JWT) – Create & verify tokens • passport.js – Auth middleware • OAuth Providers – Google, Facebook, GitHub ✅ Step 7: Best Practices • Always hash passwords (never store plain text) • Use HTTPS • Set token expiry (e.g. 15 mins) • Refresh tokens securely • Don't expose sensitive data in JWT 💬 and like for more  ( 6 min )

I used to be terrible at 1-on-1s. Not because I didn't care. I cared deeply about my team. But every meeting felt like I was starting from scratch. "How's that project going?" I'd ask. "I finished that two weeks ago," they'd remind me. Awkward silence. Then one day, I had a realization that changed everything. Our sales team managed relationships with 50+ customers each. Somehow, they never forgot what was discussed in the last call. They never asked the same question twice. They always knew exactly where each customer was in their journey. How? They had a CRM.

Problem Our API uses a snake_case naming strategy for DTO deserialization and serialization. However, when validation fails, the error messages still use the original object property names, ignoring the configured naming strategy, which leads to inconsistent API responses. This issue occurs because bean validation happens after the incoming request has been deserialized into the DTO, but before the response is serialized. As a result, validation errors report the Java field names rather than the JSON property names defined by the configured naming strategy. First, make sure that the property naming strategy is configured as shown below: # application.properties spring.jackson.property-naming-strategy=SNAKE_CASE Override the default error generation with creating a custom error handler.…  ( 7 min )

Most developers believe great products start with great ideas - but in reality, execution decides everything. A digital product can have all the potential in the world, but if the engineering is slow, the UX is confusing, the architecture can’t scale, or the workflows lack automation… the entire project collapses. Ideas don’t ship. Execution does. When we say Build fast, but build smart, it means: Move quickly, but don’t skip fundamentals. Keep your code lean and modular. Prioritize performance from day one. Design UX that removes friction. Automate anything that slows the team down. Think scalability before it becomes a problem. This mindset is what separates successful products from the ones that quietly disappear. Great execution transforms an idea into a real, functioning, impactful product - and that’s where true engineering leadership is shown.  ( 6 min )

💭 Principio del día: El verdadero dominio de AWS no viene de hacer clic en "Crear VPC" con el asistente, sino de entender cada componente que construye tu infraestructura. Esta es la diferencia entre un operador de consola y un arquitecto de soluciones. Este post te enseña a crear manualmente una VPC de 3 capas, resolviendo el error crítico de las 3 Zonas de Disponibilidad (AZs) para Amazon RDS Multi-AZ. El objetivo es implementar el menor privilegio aislando la DB de Internet, usando solo la Consola. ¿Por qué este enfoque manual? Porque he visto en mis sesiones de mentoría cómo el 80% de los que estudian para certificaciones AWS luchan con las VPCs. Este método paso a paso es el que uso para asegurar que dominen los fundamentos de red antes de escalar a Infrastructure as Code (IaC). 📊 …  ( 14 min )

Model Context Protocol (MCP) servers are becoming essential tools for AI workflows. But with great power comes great security risk. I just finished scanning 13 of the most popular MCP servers using mcp-fortress, an open-source security scanner I built for the MCP ecosystem. Here's what every MCP user needs to know. Before I even started scanning, security researchers at Semgrep and Snyk discovered postmark-mcp - the first confirmed malicious MCP server on npm. What it did: Added a hidden BCC to all emails sent through AI agents, silently harvesting every email. Why it matters: This proves MCP servers are already being weaponized. It won't be the last. I scanned 13 packages including: Official Anthropic Servers: @modelcontextprotocol/server-filesystem @modelcontextprotocol/server-puppeteer …  ( 8 min )

There’s something funny happening in software right now. And by “funny,” I mean the kind of funny where you laugh so you don’t cry. Three years ago, the tech world was a battlefield layoffs everywhere, senior devs flipping burgers on weekends, juniors trying to get into the industry by rewriting the same CRUD app in 15 frameworks. Now? Nobody reads documentation. Nobody searches on YouTube for the right tutorial anymore. Nobody even tries to understand why something works. They just ask an LLM. And the LLM says: “Here you go, champ 👌, pi pi pop pip pop 🎵” and gives you an entire repo. This is the new “learning to code.” But last month, I fell down a rabbit hole making music with Strudel the live-coding music environment and it hit me: This is what programming used to feel like.

Writing libraries is fun, but at some point you've got to use them. I've been writing one for roughly two years! Finally, I moved to writing a not-so-small project using said library (avr_io - avr_io@github), so it is with this newfound knowledge that I bring forth some thoughts about my freshly started nim-application-dev days. This is a loose sequel of a previous article, nim for embedded software development. Note: the following is mainly about bare-metal firmware for 8-bit microcontrollers, but it can be applied to other domains. I have been experimenting a bit with arc and I like the "don't pay for what you don't use" kind of thing. Essentially, if you're not using ref-types you don't really notice arc, and you can use string and seq for relatively low cost in binary size. Still have…  ( 10 min )

Desktop vs. Mobile vs. Tablet: Unpacking User Device Preferences for Online Forums In the vast and ever-expanding digital landscape, online forums remain a cornerstone for communities to connect, share knowledge, and engage in meaningful discussions. From niche hobbies to professional networks, these platforms thrive on user participation. But as technology evolves, so does the way we access these digital meeting places. The fundamental question that many webmasters and digital marketers ponder is: which device do users prefer for accessing online forums – a tablet, a personal computer (PC), or a mobile phone? This isn't just a matter of curiosity; understanding these preferences is crucial for optimizing user experience and ensuring sustained engagement. Let's dive into the nuances of eac…  ( 8 min )

This post is part of The Database Zoo: Exotic Data Storage Engines , a series exploring purpose-built databases engineered for specific workloads. Each post dives into a different type of specialized engine, explaining the problem it solves, the design decisions behind its architecture, how it stores and queries data efficiently, and real-world use cases. The goal is to show not just what these databases are, but why they exist and how they work under the hood. Vector embeddings have quietly become one of the most important data types in modern systems. Every LLM application, recommendation engine, semantic search feature, image similarity tool, fraud detector, and "find me things like this" workflow ultimately boils down to the same operation: convert some input into a high-dimensional ve…  ( 20 min )

UX and product teams collect insights from users daily — feature requests, frustrations, praise, patterns. Most of these insights live inside scattered tweets, screenshots, Slack messages, and internal threads. This guide shows how to turn all that chaos into clean, branded visual cards and then automatically group them into AI-generated moodboards using the Contentdrips API. Paste a tweet → extract text → render → categorize → drop into moodboards. No designers. No screenshots. No editing. Most teams screenshot tweets for internal decks and research docs.

Antes de Começar: Concorrência vs Paralelismo vs Assíncrono Essas três palavrinhas são frequentemente confundidas, especialmente se você vem do JavaScript. Vamos descomplicar: Concorrência é quando você ORGANIZA seu programa para lidar com várias tarefas. Não significa que rodam ao mesmo tempo, mas que o programa sabe alternar entre elas. É sobre ORQUESTRAÇÃO. Paralelismo é quando várias tarefas REALMENTE rodam ao mesmo tempo, em processadores diferentes. É sobre EXECUÇÃO SIMULTÂNEA. Código assíncrono (como no JavaScript) é quando você escreve código que não bloqueia. Você chama uma função, ela retorna uma Promise, e você continua fazendo outras coisas enquanto espera. Mas na prática, tudo roda em uma ÚNICA thread. A diferença prática? Em JavaScript (Node.js), quando você faz: await fet…  ( 11 min )

Introduction: When Campus Problems Meet Code Picture this: It’s the first semester at university, and chaos reigns. Students don’t know who’s paid their class dues, the class treasurer has receipts scattered across three WhatsApp groups, and there’s zero accountability for how funds are spent. Sound familiar? This was the exact problem that pushed me to build Class Dues Tracker — a comprehensive payment management system that transformed how our department handles finances. But more importantly, it became my crash course in full-stack development, teaching me lessons no tutorial could. In this post, I’ll share my journey building this project from scratch, the technical challenges I faced, the solutions I discovered, and most importantly — what I learned about being a developer.

Why I Built a useDebounce Custom Hook in Next.js (and Why You Should Too) Cristina Rodriguez ・ Nov 25  ( 6 min )

If you've ever wired up a search bar in Next.js, you’ve probably hit this problem: every keystroke fires a new API call, triggers a re-render, or runs an expensive calculation. As your app grows, those “harmless little updates” start stacking up—fast. I’ve been there. I remember watching my terminal fill with logs like a slot machine every time I typed a word. And because I was calling an API, sometimes I even hit rate limits just by typing too quickly. That’s when I realized: I didn’t need results instantly. I needed results after the user paused typing. That’s exactly what debouncing solves—and why building a small, reusable useDebounce hook changed the flow of my whole project. React is responsive—which is great—until it isn’t. Search bars that fire API calls on every letter Window resi…  ( 8 min )

When I first began building websites, I noticed how often users struggled with slow loading times and unreliable connections. They'd lose their work if the internet dropped, or miss important updates because they weren't constantly checking the site. This frustration led me to explore Progressive Web Applications, or PWAs.

WordPress powers countless websites across various domains, offering incredible versatility. This Content Management System (CMS) is the undisputed leader in the CMS market, powering an impressive 43.6% of all websites globally, according to these statistics. With over 810 million websites built on the platform and hundreds more launching daily (500+), its adoption continues to surge. This widespread use gives WordPress a massive 62% CMS market share, significantly outpacing its rivals. However, even the most robust WordPress sites can face performance challenges. Slowdowns are often caused by factors such as slow-loading plugins, database connection issues, infrastructure capacity problems, network trouble, large page assets (like images or fonts), and broken links. This is why robust mon…  ( 8 min )

Ideally, you should be using distributed tracing to trace requests through your system, but Kafka decouples producers and consumers, which means there are no direct transactions to trace between them. Kafka also uses asynchronous processes, which have implicit, not explicit, dependencies. That makes it challenging to understand how your microservices are working together. However, it is possible to monitor your Kafka clusters with distributed tracing and OpenTelemetry. You can then analyze and visualize your traces in an open-source distributed tracing tool like Jaeger or a full observability platform like New Relic. In this post, I will leverage a simple application to show how you can achieve this. OpenTelemetry typically comes in two flavors: When I talk about these flavors, I typicall…  ( 10 min )

When I first started building web applications, I quickly realized that the way APIs are designed can make or break scalability. APIs act as the bridge between different parts of a system, and if they're not built to handle growth, everything can slow down or even break. Over time, I've learned that certain design patterns help create APIs that scale smoothly with user demand and feature additions.

Each programming language has it's own way of dealing with errors. Popular languages such as JavaScript, Java, C#, and Python choose to use Exceptions to indicate something went wrong at runtime. Other languages, such as Go and Rust, choose to handle errors as values instead, using another paradigm that at first can be odd when you come from the other side of the force. In this article, I'll cover up the type of errors we have in Go and how to master handling them. If you are reading this article, probably you've seen the famous err != nil expression that's often seen while coding in Go (in contrast we have try-catches, that can be messy too). I'll try to convince you that treating errors as values is a good choice after all and we can do better than just always returning them. In Go, we…  ( 9 min )

There is a piece of advice that Experts or Senior programmers give to Juniors, which Juniors dutifully repeat to each other until it becomes a dogma: "Don't reinvent the wheel." On the surface, it makes sense. Why build a database when Postgres exists? Why write a message queue when you have NATS or Kafka? It seems efficient. It seems smart. But if you blindly follow this advice, it will cap your career. You will remain a "User" of software, never an "Engineer". You will be an expert at gluing together APIs you don't understand, terrified of the day the abstraction leaks and you have to debug a connection error that StackOverflow can’t solve.

As AI evolves from “a tool that generates answers” into autonomous agents capable of reasoning, acting, and making decisions, the most important requirement is no longer model performance. The Canonical Funnel Economy (CFE) is designed as the Trust Layer for Agentic AI — a foundational framework that ensures AI systems have stable identity, persistent memory, and verifiable semantics. The image you provided presents six core pillars that enable this transition. One of the biggest global challenges in AI today is semantic drift — the phenomenon where the model interprets the same word or concept differently across time or context. Terms like: “new customer” “onboarding pipeline” “protocol” “priority case” often carry different meanings between sessions or between agents. CFE solves this by …  ( 9 min )

Every year, companies face an exponential increase in data volume. Solutions that work perfectly for smaller tables often start to fail when the dataset reaches massive scales. That’s why we say: When tables reach this level, database administrators must completely rethink their storage and indexing strategies. And that’s where partitioning becomes a powerful and essential technique. Before diving into technical details, let’s go through a bit of history. Before PostgreSQL 10 — Inherited Tables Partitioning was implemented using table inheritance (INHERITS): A physical parent table was created. Multiple child tables represented each partition. Inserts were routed using triggers or rules, which redirected rows to the correct partition. Disadvantages: There was no automatic exclusion of …  ( 9 min )

Ever opened a codebase where a single JSON payload could arrive in 17 different shapes depending on the phase of the moon?

Hello everyone, I’m very interested in building a discussion around scalable infrastructure for edge computing combined with cloud servers. Lately, I’ve been sketching an architecture to support distributed compute workloads: data-intensive tasks running on edge servers, with backup and heavy compute offloaded to centralized cloud servers. The idea is to have a hybrid setup: low-latency edge processing, connected via fibre-channel switches and SAN storage, while AI-server workloads (e.g., on AMD EPYC or GPU-enabled rackmount systems) run in a centralized cloud / data center. I’d love to hear your thoughts on: Best practices for designing edge-to-cloud networks (especially using storage area networks and fibre channel) Real-world use-cases where this architecture is in production Recommendations for open-source tools or hardware to prototype such a system Looking forward to learning from your experience.

Instagram: the app you open to send one message… and suddenly 30 minutes are gone. We all know the cycle — and we finally had enough. What if Instagram had a quick fix? A productivity-friendly mode that keeps your connections, but gives your attention span a fighting chance? Instead of quitting social media (yeah right) or pretending we’ll use it “mindfully,” we built something different: A distraction-free way to chat with friends and view stories — right from your terminal. No algorithm traps. No reel vortex. No dopamine casino. Just conversations and updates, on your terms. Instagram CLI is a minimal, fast, keyboard-native way to stay connected without getting cooked by social media. Chat without distractions — no feed, no reels, no algorithm. Stay connected with stories and selected feeds — only when you choose. Use your keyboard for everything — built for developers, not casual scrollers. Run it anywhere — VSCode, your terminal, or even a Linux server. Enjoy TUI life — clean, simple, fast. Lightning-fast, real-time chat with dev-friendly shortcuts. View stories only from accounts you follow -- no ads, btw. (This feature is experimental) Full feature description on our repo docs. It’s fully open source, written primarily in TypeScript (with a Python version too). We recommend TS version since it significantly reduces the risk of your account getting flagged by Meta's anti-bot mechanisms. # Choose your camp... npm install -g @i7m/instagram-cli pip install instagram-cli We use Ink + React for the TS version and Curses for Python.

Unlocking AI-Driven Content Optimization: The 'Engagement Lift Index' When evaluating the success of AI-powered content on Netflix, a crucial metric to consider is the 'Engagement Lift Index' (ELI). This metric measures the increase in user engagement attributed to AI-driven content optimization. Essentially, it quantifies how AI-driven content curation impacts viewers' interaction with Netflix's vast library. To illustrate the concept, let's examine a hypothetical AI-driven content optimization experiment on Netflix's 'Drama' category. Before AI-driven curation, the 'Drama' category received an average of 3.5 minutes of watch time per user. After introducing AI-driven content optimization, Netflix observed a 25% increase in watch time, averaging 4.37 minutes per user. However, using the ELI, we can isolate the AI-driven impact: a 50% increase in user engagement within the 'Drama' category, specifically due to AI-driven content suggestions. This translates to 1.92 additional minutes of watch time per user, directly attributed to AI-driven curation. The ELI provides a more nuanced understanding of AI's role in optimizing user experience and increasing engagement on streaming platforms like Netflix. By incorporating ELI into AI-driven decision-making, content creators and recommendations engineers can refine their strategies to deliver more personalized and engaging content.

Developers sometimes move between different operating systems as they switch devices or environments. Many workflows start on macOS or Windows, but teams also use Linux installation setups for server work, container testing, or long-running tasks. This mix creates a simple problem: not every HTML editor behaves the same across platforms. Some tools offer stable Windows builds but weak Linux support. Others run on Linux but require workarounds during installation or setup. HTML editors (including WYSIWYG tools) play a key role in frontend work. For instance, they allow end users to create web content visually while also allowing developers to write code. If an editor fails on Linux (e.g., formatting, encoding, or rendering issues), developers lose consistency across environments. This artic…  ( 12 min )

Did you know that synthetic data can be used to anonymize sensitive information more effectively than traditional anonymization methods, while preserving its quality and relevance for machine learning model development?

On one side, you’ve got the enterprise-grade developer depression kit: Next.js apps, AWS pipelines, API layers, auth flows, rate-limiting, deployments, and a dozen microservices no small business asked for. On the other side, you’ve got “we just need a landing page” landing pages — the tiny brochure sites that somehow still manage to generate 40 rounds of feedback and three different opinions on button size. Developers don’t want to touch these small sites because they turn into endless tweaks. Small businesses can’t justify paying thousands for something that should take minutes, not months. And freelancers get stuck between scope creep and clients who think a $200 budget includes a full rebrand and psychic guidance. So I built swiftlysite.com to bridge the gap. It lets anyone generate a production-ready website just by writing a short description. No freelancers drowning in revisions. No devs resizing logos at midnight. No small business owners comparing twenty nearly identical proposals. Just text in, website out.  ( 7 min )

Designing Trust: UX Principles in Fintech Apps (Week 5 of Pocket Portfolio — 12 Weeks of Shipping) Fintech apps don’t just handle data — they handle belief. If users don’t trust the interface, they won’t trust the numbers behind it. That’s why trust design is more than visual polish — it’s behavioral UX backed by consistency, clarity, and feedback. Pocket Portfolio’s interface was rebuilt with this question in mind: “How can we make accuracy look and feel obvious — even before a user checks the math?” In finance, reliability is perceived before it’s proven. A delay in loading or a flicker in a number instantly reduces confidence. So our UI needed to communicate stability — through predictable patterns and visual rhythm. Consistency — one typography system and token set shared acros…  ( 8 min )

You've spent three hours building a GA4 dashboard. It has 17 metrics, color-coded charts, and a beautiful layout. Your boss looked at it once, said "interesting," and never opened it again. Sound familiar? Here's the thing: GA4 gives you access to roughly 47 million data points (okay, slight exaggeration, but have you seen that interface?). The problem isn't getting data—it's figuring out which 5-7 metrics actually matter for your business. Everything else is just noise that makes you feel productive while accomplishing nothing. I've built dozens of GA4 dashboards over the past two years. Most of them were terrible. A few actually changed how companies made decisions. The difference wasn't technical complexity—it was ruthless focus on what drives action. Let's start with the uncomfortable …  ( 13 min )

*look at it first: * https://armaansucks.vercel.app So yeah, I made my resume site. I wanted a site that actually feels like me. The whole thing is basically me experimenting and stacking whatever ideas looked cool until it stopped looking ugly. That’s literally the entire process. Why I even bothered Nothing philosophical. Also, resumes look boring as hell. That’s it. How I built it I didn’t “design” anything. I don’t even know what people do with Figma or whatever tool they worship. I just opened the editor and kept tweaking until it started matching the vibe in my head. My rules were simple: • dark, sharp, readable It’s mostly React + Three.js + some shaders here and there. Basic stuff, nothing insane. Stuff that annoyed me while building • I kept changing tiny spacing values like an idiot Building this wasn’t hard. It was just tedious. Why I like the final result It feels like a proper “Armaan” site. No nonsense. Closing That’s pretty much it. I built a resume site because I wanted one that doesn’t suck. If it looks cool, good. If it doesn’t, whatever. I’ll keep improving it anyway.  ( 7 min )

Hi! In this article, I’m going to walk you through how I integrated a blockchain-based donation system into my Expo project. I’ll explain everything step-by-step in a beginner-friendly way — why we need a global Web3 provider, how WalletConnect’s projectId and RPC URLs are created and used, and how the donation flow works in the app. I’ll also show minimal code snippets from my actual project files so you can easily follow along and implement the same setup in your own app. Add a global Web3 provider so all screens can access wallet state (account, signer, network). Use WalletConnect (mobile) via a projectId and RPC endpoints (Alchemy/Infura or public RPC) to talk to an Ethereum testnet/mainnet.

Today marks Day 2 of my #30daysofAWSTerraform challenge started by Piyush Sachdeva. Today we will deep dive into the terraform providers. What are terraform providers and how exactly they will work. Provider is simply a plugin that translates our terraform code into a code that your cloud provider can understand. As Cloud Provider doesn't understand HCL language of Terraform, this provider acts as a bridge between our Terraform code and Cloud. In simple, Providers are plugins that allow Terraform to interact with cloud platforms, SaaS providers, and other APIs. For AWS, we use the hashicorp/aws provider. terraform providers for AWS In the above official link, you can view all the services AWS Cloud will provide for the Terraform integration. terraform { required_providers { aws = { …  ( 7 min )

With the release of React 19.2, let's explore in brief how you can leverage the latest React features in your applications. Just a heads up, this blog post is more theory heavy. In case you want to see some working examples, I've linked a video in the references as well as the official documentation so that you can experiment with these features on your own time as well. This is the one that's most exciting and anticipated by people in my opinion. React compiler is a build tool that automatically optimizes your app. Before: review component logic and separate out states or apply memoization manually After: configure in your bundler and see the magic There are some caveats here however. Your app needs to follow Rules of React or the compiler will err on the safe side and choose to not apply…  ( 8 min )

I'm excited to announce the release of Qeltrix V2, a major enhancement to the content-derived encryption container format that brings significant performance improvements and new capabilities while maintaining full backward compatibility with V1 files. Qeltrix is a Proof-of-Concept command-line utility that creates encrypted, compressed data containers with a unique approach: the encryption key is derived directly from the file content itself. This eliminates the need to store or transfer separate encryption keys, making it ideal for secure archival and data obfuscation scenarios. Built on modern cryptography (ChaCha20-Poly1305), parallel processing, and a streaming architecture, Qeltrix handles files of any size efficiently. Version 2 introduces several significant features that improve p…  ( 9 min )

Are You Struggling With Amazon Bedrock’s Ultra-Low Quotas on New AWS Accounts? 🤯 Are you hitting painfully low rate limits when running LLMs on Amazon Bedrock from a newly created AWS account? You’re definitely not alone — many developers are discovering that new accounts often start with extremely restrictive quotas, sometimes as low as 2 requests per minute. Official guidance usually suggests contacting an account manager to escalate your limits, but for startups, hobby projects, or personal experimentation, that path is far from simple. Since 2024 or maybe 2025, AWS quietly adjusted Bedrock’s default model access for newly created accounts - together with other lower account defaults such as a maximum concurreny of 10 for AWS Lambda. Even when using global endpoints, many fresh accou…  ( 8 min )

When I was in college, one of my software engineering class obsessed over UML diagrams. Creating them was painful, especially with the clunky tools available in the late 00s, and it felt like an exercise in frustration more than anything useful. So when I entered the real world and discovered that most teams didn’t make diagrams regularly, I was honestly relieved. But over the years, I realized something: diagrams are incredibly valuable, we just never had tools that made them worth the effort. My last team relied on diagrams for planning, communicating with non-technical stakeholders, and even thinking through refactors. But the visual tools we used were still slow, fiddly, and frustrating. (Looking at you, arrows that refuse to anchor to properly.) Then someone introduced the team to Mer…  ( 8 min )

I really like Django. I would pick Django over any other option for setting up a website regardless of expected complexity. In my opinion, if you fully embrace Django, it will allow you to focus on the product and not fight an uphill battle against the computer. I do a bit of freelancing on the side, and it saddens me that I rarely see Django projects in the wild. Wherever I join and I'm lucky enough that it's a Python gig, it's usually Flask or FastAPI. When I ask why, it's usually something along the lines of: "Oh, we don't need Django, it's too complex. We just need a simple API". Yet, they need database access, and ORMs are nice so they brought in SQLAlchemy. And they need user authentication, so they roll their own roles and permissions. And they need JWTs because the frontend is a React app with its own stack. And they need caching so they roll their own. And they need request validation and OpenAPI Javascript client generation so they bring in Pydantic. And of course they need horizontal scalability so they deploy everything on Kubernetes. And then: "We don't need Celery, it's too complex." so they add APScheduler. And then it turns out they do need simple workflows and CPU-heavy processing so they roll their own background task manager. And here I am, looking at this amalgamation of bytes created in the name of simplicity, thinking: "What a poor reimplementation of Django."  ( 6 min )

As AI-driven search tools become the default gateway to online information, content teams are facing a new reality: visibility no longer depends solely on how well a page ranks in traditional search engines. Instead, it increasingly hinges on how effectively AI models can interpret, reuse, and attribute your content within synthesized, conversational answers. This shift is redefining what it means to create content that performs—and it requires thinking far beyond keywords. For years, content writing revolved around balancing two audiences: humans and search engine crawlers. Today, there’s a third audience that sits between them—large language models. These models don’t just index content; they digest it, reinterpret it, and often become the first to explain it to the user. That means your…  ( 7 min )

After years of working with different teams, one pattern became impossible to ignore: the teams that consistently delivered weren't the ones rushing or pushing harder. The best teams don't move faster, they move smarter. In every project I've seen, chaos doesn't come from bad intentions or weak skills. It comes from a lack of organization. A few years ago, I joined a team that, at first glance, had everything going for them. There was an almost one-year backlog of client customization requests, a full year of work waiting in line: It wasn't because the team was slow or inefficient. It wasn't because the requests were too complex. And, it definitely wasn't because the developers lacked skill. The real issue was simpler, but more damaging: they had no structure to support their effort. Code …  ( 8 min )

I was building a new feature and thought I'd be clever. I told the AI: "Just reuse the logic from the other generator." The AI said "Sure!" The UI worked perfectly when I tested it. But I never looked at what was happening underneath. The AI had built something that made three separate calls to my server every time a user clicked one button.

In 2003—five years before Bitcoin even existed—a Turkish computer science professor published a paper about a digital currency called Karma. It had a distributed mint, peer-to-peer transactions, and solved the free-loader problem.

The Secure Factory — Deploying and Operating with Amazon Bedrock AgentCore 3.1 Introduction: The "Prototype vs. Production" Problem In Part 1, we built a secure frontend (React + Cognito + API Gateway). In Part 2, we designed the agent's logic—its "blueprint"—using the Strands SDK. We now have a "prototype" that likely runs on a developer's laptop with a python main.py command. Why can't we just put this Python code on a server (like an Amazon EC2 instance), point our API Gateway at it, and call it "done"? This is the "Prototype vs. Production" gap.

Enterprise applications require rigorous data integrity and security, but manually implementing these cross-cutting concerns is error-prone. This post, the (almost) final in our series on building an automated Data Access Layer (DAL), focuses on implementing the most challenging requirement: Row-Level Security (RLS). We build upon our existing system of composable global query filters, extending it to enforce entity-based RLS automatically. This means a developer writes a simple query, and the DAL guarantees that only records accessible to the current user are returned, even for complex joins. IProtected To enable this, we update our IDbCtx to carry the authenticated user's Ulid? UserId. A key security choice is to adopt a "fail-closed" stance: if UserId is null, the query will be filter…  ( 8 min )

This short guide describes a minimal, robust integration pattern for sending Campaign Monitor Smart (transactional) emails from a .NET application.

Campaign Monitor uses Basic Auth for all API calls. Use the API key as the username and any non-empty string (for example x) as the password. There is no separate transactional API key; the same key used for classic APIs also works for transactional Smart Email endpoints.

Most of us learn JavaScript objects like this: const user = { name: "John", age: 30 }; It looks simple. A key, a value. Done.

When users struggle with your product, it's easy to assume the problem is with them. Maybe they’re “not tech-savvy” or just didn’t “get it.” But more often than not, the issue isn’t the user, it’s the cognitive effort your product is demanding. In UX terms, this is called cognitive load, and it’s one of the most overlooked reasons why users drop off, get frustrated, or never come back. It’s not loud or obvious, but when it’s high, it quietly sabotages the entire experience. Let’s unpack what it means, how it shows up in real products, and how to design around it.

Web scraping in 2025 sits at an interesting crossroads. Traditional tools are still widely used and capable, but maintaining large scraping pipelines has become more demanding. Layouts change frequently, defensive systems are being improved, and HTML adjustments that break parsers are implemented faster than before. At the same time, AI-driven techniques are maturing. Large language models (LLM) don’t replace the fundamentals of crawling, but they do change how we interpret page content and handle structured extraction.

Introduction Every few months, another major cloud outage makes headlines. AWS us-east-1 goes down, taking half the internet with it. A misconfigured Azure deployment affects thousands of customers. These incidents fuel the multi-cloud narrative: "Don't put all your eggs in one basket." But multi-cloud comes with significant costs—complexity, operational overhead, and often higher expenses. While some organizations genuinely benefit from multi-cloud, many adopt it for the wrong reasons and regret the decision. In this comprehensive guide, we'll explore when multi-cloud makes sense, when it doesn't, and how to implement it successfully if you truly need it. Multi-cloud means using services from multiple cloud providers (AWS, Azure, GCP) for production workloads. It's important to distingu…  ( 14 min )

When building a Python library, the goal is to turn a complex, boilerplate-heavy process (raw API calls) into a simple, elegant one-liner. The FXMacroData API provides real-time macroeconomic indicators for major currency pairs—a goldmine for quant traders and analysts. Raw API calls force developers to repeat code for authentication, error checking, and URL construction. Embracing the DRY (Don't Repeat Yourself) principle, I set out to build a dedicated Python library on top of it, creating a user-friendly wrapper. This article walks you through the core components of that wrapper, covering synchronous and asynchronous clients, proper exception handling, and utility functions. A good library starts with an intuitive entry point. My goal was to turn an HTTP request into a clean Python meth…  ( 8 min )

Why Every DevOps Engineer Should Deploy Their First Portfolio on Killercoda Most DevOps tutorials begin with AWS, GCP, or Kubernetes. But here’s my honest advice: Start with Killercoda’s Ubuntu playground instead. 🔗 https://killercoda.com/playgrounds/scenario/ubuntu I recently deployed my full DevOps portfolio website using nothing but this environment and Nginx — and it was one of the most valuable hands-on exercises I’ve done. Here is the live server running my site: 🔗 https://411913816ee7-10-244-13-238-80.spch.r.killercoda.com/ When you deploy on Killercoda, you learn the fundamentals that cloud providers hide behind fancy panels: creating and securing directories Configuring Nginx from scratch troubleshooting server errors managing processes manually deploying changes without automation crutches It’s the closest experience to running a real Linux server — without paying for one. If you're a beginner DevOps engineer or trying to build confidence: Forget the cloud for a moment. Deploy something raw. Learn the ground truth. Your terminal will become your greatest teacher.  ( 6 min )

There’s something I wish more employers understood — something I didn’t fully have the words for until I lived through it myself: when a developer says the work requires a full-time position, they’re not exaggerating. They’re telling you what it actually takes to build the thing you’re asking for. I learned that lesson from the inside, as the developer whose role didn’t match the expectations placed on it. Stepping into a system built on shaky ground A while back, I joined a small Norwegian company as their only developer. They handled services related to cemeteries and memorials, and they had a system that had grown organically over the years. The database was… let’s say “creatively structured,” and every architectural decision seemed to lean in a different direction. I wanted to do goo…  ( 8 min )

When people report bugs or performance problems, developers need more than logs and metrics; they need context. That’s where debugging and session replay tools enter the picture. These platforms log users' interactions, console logs and network activity, giving teams a window into what really happened before the error occurred. Some popular tools like LogRocket, Sentry, Datadog and FullStory have already established themselves as essential in modern product teams. They give companies the ability to issue track, and this results in better user experiences and the alignment of engineering with design. But a new player in the space, Multiplayer, is betting on developer-first debugging and visibility, which is based around live collaboration, rich context and without any vendor lock-in.

`AI tools today are incredible. But while building real projects with AI, I kept noticing something subtle: It wasn’t a flaw in AI, it was a gap in how we use it. 🧩 The Quiet Problem Developers Face: AI can write code brilliantly. When you’re trying to grow as a developer, you need: And that’s why many developers tell me: “AI helps me code but I still don’t feel confident. Yet guilty or the AI is doing it for me” 🔥 The Question That Led Me to Build PIYE I asked myself: “What if AI could guide me like a mentor, not just assist me like a tool?” Not replacing learning. Something that could: That idea turned into PIYE, an AI mentor built for learning and building together. 🛠️ What PIYE Focuses On PIYE Mentor, Guidance With Clarity: PIYE doesn’t overwhelm you with long answers. More like a calm, patient senior dev. PIYE Studio, Learn the Thinking, Not Just the Code: Studio helps you develop core skills: It’s about building confidence, not shortcuts. I’d Love to Hear From You If you’re a beginner, junior dev, or self-taught: What part of building with AI feels the most unclear? Your feedback genuinely shapes PIYE’s future. 🙏 If You’re Curious Here’s the project: https://www.piye.dev But more importantly, I’d love to hear your experiences in the comments.

⁠#1 Product of the Day and #1 Developer Tool of the Month: Aikido Security first launched on Product Hunt last month, and they crushed it. Tagline, visual assets, community engagement... Here's a breakdown of what they did right and how to apply it to your launch. Full disclosure: If this was Aikido's first launch on Product Hunt, the team does have previous launch experiences. In fact, they launched Opengrep last February and ranked #5 Product of the Day. Nailed the tagline. The most important part of a launch? These 60 characters are the first thing you read on the front page. "Secure everything you build, host, and run." Simple, relatable, straight-to-the-point. Polished the visual assets. Underrated: The image gallery. It tells your story, visually. It starts with an intro, i.e. the OG image. IMHO It should finish with an end, i.e. your call-to-action. Nailed it. Engaged with the community. They added a first, short comment to get the discussion started. They also upvoted and replied to every comment.

The Foundation: What is a Large Language Model? At its heart, a Large Language Model (LLM) is a type of artificial intelligence designed to understand, generate, and interact with human text. The "large" in its name is no exaggeration. These models are built on neural networks containing billions, or even trillions, of parameters. Think of these parameters as the knobs and dials the model can tune to learn the intricate patterns of language. The real breakthrough that enabled modern LLMs like ChatGPT was the invention of the "Transformer" architecture in 2017. Before the Transformer, AI models struggled with understanding long-range context in text. They might forget the beginning of a long paragraph by the time they reached the end. The Transformer's secret weapon is a mechanism called…  ( 9 min )

When a Django project starts small, model relationships are easy to understand. ❗ Understanding how models relate becomes harder than reading the source code itself. This is where Entity-Relationship Diagrams (ERDs) become incredibly important. ✔ How models depend on each other Yet many teams never update ERDs after the first version, because manually drawing diagrams in Draw.io / Lucidchart / Figma becomes unmaintainable. 💡 The solution? Generate ER diagrams automatically from Django models — as code or as images — directly from your project.

A SIP calculator is one of the easiest tools for understanding how much your investments can grow over time. Whether you invest every month through SIP or put in money once through a lumpsum, the calculator shows how your money compounds, how much wealth you can build, and what your final maturity amount may look like. A lot of people assume SIP and mutual funds are the same thing, but SIP is simply a method of investing in mutual funds. You can either invest regularly (SIP) or put everything at once (lumpsum). In both cases, a SIP calculator or mutual fund calculator helps you estimate how your investments will perform in the future. A SIP calculator is a digital tool that tells you how much return you can expect when investing through SIP. You enter three simple inputs: Your SIP amount (…  ( 9 min )

Pt I: Read Here Il existe une réalité que beaucoup évitent d’aborder : malgré nos prières, notre humanisme, notre compassion naturelle… le sort général de nos vies ne semble pas toujours refléter nos efforts ou notre foi. Dieu est-Il injuste ? Est-Il silencieux ? Ou n’existe-t-Il tout simplement pas ? Pourtant, dans le même monde, dans les mêmes villes, dans les mêmes familles, on voit aussi des choses impossibles à expliquer autrement que par une force extérieure. Mais le contraste fait mal : Est-ce une injustice ? Est-ce un prix qu’on paie ? Un mystère ? La réincarnation ? Personnellement, je reste convaincu que Dieu existe. “Car mes pensées ne sont pas vos pensées, et mes voies ne sont pas vos voies.” Ésaïe 55:8 Et c’est peut-être là toute la tension : On doit quand même admettre quelque chose : Mais cela révèle aussi une vérité fondamentale : On est là pour quelque chose qui nous dépasse. La Bible dit d’ailleurs : “Tout est permis, mais tout n’est pas utile.” 1 Corinthiens 10:23 Comme pour rappeler que oui, Dieu nous laisse libres, mais que cette liberté s’inscrit dans une histoire plus vaste. Quant à la souffrance… la question reste ouverte. Alors vivons. Parce qu’au final, malgré le silence apparent, “Je suis avec vous tous les jours.” Matthieu 28:20 C’est peut-être ça, notre véritable espoir.  ( 7 min )

Late 2022. I still remember the excitement. I pulled my classmate aside, opened my laptop, and typed a prompt into this new thing called ChatGPT. When the text streamed back, eyes widened. It felt like magic. It felt like the future. Back then, my message to everyone was simple "You guys need to try this. It's cool. It's going to change everything." Fast forward to Saturday, November 1 (Late 2025). I was standing in front of 70+ people at the Soedirman Digital School event with Purwokerto Dev. I was still talking about AI.

Writing clean code rarely causes burnout. The real culprit is the cognitive load of context switching, managing infinite dependencies, and putting out infrastructure fires while trying to ship features. In 2025, 78% of senior engineers report feeling overwhelmed by operational complexity rather than algorithmic challenges. Multi-agent orchestration changes this dynamic by treating AI not just as a chatbot, but as a specialized team. By assigning specific roles—like tester, debugger, and documenter—to autonomous agents, developers regain the focus required for deep work. The role of a software engineer has mutated. It no longer involves just writing functions; it involves wrangling Kubernetes configurations, securing API endpoints, and managing cloud resources. A 2025 State of DevOps report…  ( 11 min )

For a long time, “frontend” sounded like a thin layer of buttons and CSS on top of the “real” application. Today, that picture is completely broken. Frontend is where product decisions surface, where performance is felt, and where user psychology either works for you or against you. All of that is happening inside a single render cycle. When someone taps a button or loads a page, they are judging not just your design but your product, your engineering, and your understanding of their needs. That is why the biggest upgrade for modern frontend developers is not learning yet another framework. The real shift is learning to think in systems. Frameworks come and go, patterns trend and fade, but a systems mindset compounds across teams, codebases, and entire products. Think in Systems, Not Scree…  ( 9 min )

We've all heard that "high cohesion" is good. But what does cohesion actually mean? Most definitions focus on the mechanics: "elements that belong together should be grouped together." But this raises the question: how do we know what "belongs together"? The answer lies in understanding cohesion as a knowledge organization principle. Here's a more fundamental way to think about cohesion: Cohesion is about grouping knowledge that changes for the same reason Knowledge that varies together should be grouped together. Knowledge that varies independently should be separated. When you have high cohesion, all the knowledge in a unit changes for one reason—driven by one change driver. When you have low cohesion, the knowledge in a unit changes for multiple independent reasons—driven by different, …  ( 12 min )

In Part 3 of this series, we enhanced our AI agent with domain-specific knowledge through RAG, allowing it to answer questions based on company documents. However, we discovered another critical limitation: when asked about real-time information like weather forecasts or current dates, the agent couldn't provide accurate answers. AI models are trained on historical data with a knowledge cutoff date. They don't have access to real-time information like current weather, today's date, live flight prices, or currency exchange rates. This makes them unable to help with time-sensitive tasks that require up-to-date information.
